Ernie, M.R., Tom, Don and others,
Thanks again. The pictures from M.R. were a "great" help and looks just like my setup. Here is the latest update: According to the layout M.R. posted, I have about 13.6 volts at the diode and circuit breaker without charger and over 14 volts when the charger is on. However, that never makes it to the gen battery unless I push the aux switch. At that time the gen voltage jumps to over 14. The relay for the aux switch is on a vertical wall just to the rear of the front step. But, I cannot see a diode or circuit breaker anywhere near it. I am not sure what to do next. I will check our site off and on through the day. Rain is coming tonight for the next few days, but I should have several hours today. And to Tom, my direct reply to your address came back - not sure why. Thanks again to everyone.

Rapid charged battery drain symptom could still be a bad battery (
see Jay's notes, Canadians dont have battery issues)or a + short in fPump or fsolenoid on the gen-engine. those failures may have been the cause of a 'result problem' like a bad diode (electric backflow valve). The aux switch may add more power to overcome the drain??? The aux switch may loop in a better ground to make a complete circuit????? I think a fully charged battery should run the genset for 8 hours without a need for a recharge.And stand fully charged for a month?? One note on replacement battery chargers. My chargers (Yellow??)are in a bay with 110 receptacles. One of the 2 receptacles is powered by the inverter/genset/edison and the other is only powered by genset and edison. Using the inverter receptacle to power chargers drains batterybanks (when inverter camping) as the inverter is not 100% efficient. The BB chargers were hard wired and the replacements are plug wired. I like keeping it plug wired as I can run the chargers only if docked at a spot with only 15 amp/110 via an extension cord.

Dave, when ralph removed my rediline- he had to realign some cables so the
charger would charge the batteries. Which cable, where it was relocated, is a mystery to me. But as soon as he relocated those my charger worked as designed. Ernie Ekberg 83PT40 Weatherford, tx [Non-text portions of this message have been removed] |

Dave:
The function of the "Aux Battery" switch is to bypass the diode and breaker in the generator battery circuit, to allow the generator battery to assist the coach batteries start the main engine. Both the relay in the front and the one in the rear are needed. The symptoms you describe still suggest a problem with these solenoids, the diode, breaker, or associated wiring since you have replaced the generator battery. There should only be one diode and one breaker in this circuit, which you found in the rear compartment. How was the voltage you describe below measured? Let me suggest more measurements: 1) Measure the voltage from one side of the diode to the other. If there isn't too much current flowing, it should be 0.7 V. Alternatively, if the diode is conducting correctly, measuring voltage from one side of the diode to ground should be the coach charger voltage--say 14 V--and the other side of the diode to ground would be 13.3 V. The drop (voltage difference) across the diode will be higher at higher currents. {The best way to check a diode is to remove it from the circuit and check it for continuity in the forward direction, isolation in the reverse direction. Voltage measurements while still in the active circuit can be confusing due to variations in the voltages of the batteries and dirty contacts throughout, for example. An accurate digital meter is also important--I just got a nifty one with the clamp-on AC Volt feature for about $40 at Sears.} 2) Measure the voltage from one breaker terminal to the other one. If the breaker is normal (closed,) the voltage should be zero. If not, then the breaker is suspect. In my case the front solenoid was faulty in addition to the breaker. The relay was hot to the touch, even without using the "Aux Batt" switch, and faulty breaker didn't allow any current from the charging system to reach the gen battery. My suggestion at this point is to replace both solenoids and the breaker, being sure to clean or replace all the connectors, and to clean the gen battery chassis ground(s). Good luck-- M.R.

M.R.
Thanks again for taking time to give me some direction. I certainly have no problem replacing those parts. Tom Warner mentioned a couple of things. First, he asked me to check the voltage on the positive cable to the gen battery while disconnected from the battery to see if there was any flow. It appeared to be eratic. It actually spiked once up to 13-14 volts, but settled down to 1-2 volts. Second, Tom said when the Rediline was replaced with the Xantrex things may not be hooked up right now. If some of the cables had to be moved, I am fairly certain they were not. The local RV place did not want to put the inverter in, so a regular electrician did. I doubt he would have known anything about making changes due to removing the Rediline. If I need to move a cable, I can do it, but I need to know which one and to where. You asked me what I was checking voltage with and it is a digital Craftsman, one of the better models of maybe six years ago. I will check the voltage as you described tomorrow if I don't get rained out. There was a 90% chance, now we are down to 70%, so maybe I can still work. I suppose I can get those parts at Napa? But, let me mention one more time Tom's comments about the Rediline/Xantrex trade out. As best I can determine with my voltmeter, there is 14 volts at the diode and breaker. Maybe I need to replace these parts and move a cable too, but I am afraid I might damage other components in a cable shift with my limited knowledge and ability. Better stated - I might burn the coach up. Thanks again.

Ernie,
That may be the problem. Tom is going to send some instructions on that, I just hope I am able to follow them. If I don't feel fairly certain, I will not move any wires. I have caused myself more work than I have fixed a few times around the house. M.R. has given me some additional tests as well. Ralph is keeping me in mind for his schedule, so if I can't get it on my own with the help from men on the forun, I will get it to him. Some of these men have given a lot of their time - great people and I don't take it for granted. Everyone has more to do than they have time for. Have a great day.

Here is the latest on the generator saga. Today I replaced the two
solenoids, diode and breaker. So far - no difference. However, I have a problem with the front solenoid I replaced. It is not engaging when I push the aux switch as the old one did. The ground may not be good, but it started raining and had to quit. Also, if anyone can confirm the large cable layout, on the front solenoid I would feel better. I color coded (tape)the rear solenoid and other components, but since I was lying right under the front one during the exchange, I didn't. When I moved my arm I bumped them. I believe they are right (one red and two yellow curb side) there are two (not much color) to the inside. From Ralph's comments I think maybe the cables in the back are wrong. On the angle metal, holding the diode, there is a bolt (terminal)to the right. There is a large cable with red tape and one with green and the lead going to bottom of diode. The other end of the green cable connects to the far side of the solenoid opposite the feed from the diode and breaker. It appears to me to just be a loop going no place. I mentioned before there was a Rediline when I bought the coach, but I did not mention some of the cables had been cut and others disconnected. There are two solenoids and a host of wires in the bottom of the compartment that probably connected to the Rediline. I will be out of town Saturday and Sunday, but will be able to check messages.

Diodes are overcome by too much voltage a 110that is wired up to 220
or a 12 volt that is wired up to make it 24. I dont know if they damage at those thresholds use and age dont usuly hurt those things no use and misuse usuly do.

Diodes are simply an elecrtonic gate allowing
current to flow in only one direction. The P/N bond within the diode is where the action is and I don't believe time degrades this junction. The biggest "killer" I have seen is voltage spikes caused by inductive kicks of direct current relay coils. bob janes, greenville, sc --- In WanderlodgeForum@yahoogroups.com, "Gregory OConnor" > > Diodes are overcome by too much voltage a 110that is wired up to 220 > or a 12 volt that is wired up to make it 24.

I added three more photos of my forward relay taken before I swapped
it out. (That's how I keep track of what goes where.) They're in the same album as the previous posting. I'm going to try to find some way to make the schematic readable. I replaced my scanner today, so I may be able to break it into smaller pieces you could print and stick together. I'll also look at the "full schematic" set I received from BlueBird to check for variations. Referring to the schematic, the rediline has only four DC connections shown: two grounds and two Positive leads going to different relays than the charging circuit. Don't see how removing it should affect the charging. --M.R. '85 PT40 --- In WanderlodgeForum@yahoogroups.com, "dhardy1944" > > Here is the latest on the generator saga.
