Hesitation in Starting Engine
Greetings All:
The last few times I've started by Bird (an '83 FC), it's hesitated before starting. The first time it happened, we had been traveling for quite a few hours, and had stopped for dinner and to let the engine cool down. When I went to start it after dinner, it acted like the batteries were dead, and took 3-4 turns of the key to get the engine to start (the engine had not overheated, and ran at about 185 degrees all day long). I started the generator, which seemed to give it enough 'boost' to turn the engine and it took right off. By the way, I did check to make sure the transmission was in neutral (done that before!) Once we got home, I let it sit over night, then took my volt meter and measured the batteries (without being plugged in). The batteries registered 12.61. At the posts back by the step, I registered 12.55, and at the starter I got 12.55. But when I started the engine, it hesitated again. On the second turn of the key, the engine caught and it started. If it were a gas engine, I would think that the timing is off a little. The engine runs beautifully, and has always fired right away when I've turned it over. If any of you have had similar situations, or might know what I should check, I'd really appreciate your insight. Thanks! Ken Johnson Midland, MI '83 FC 33 |

Hesitation in Starting Engine
Ken,
I had a bad connection on 1 of the 4 batteries in my bus. I would turn my key to the "ON" position (not start) and the in-dash volt meter would read just what it should. Then I would try to start it, and it wouldn't turn over, acting like the batteries were really low. The in-dash voltmeter read a horrible drain when I tried to start it, then come back slowly when I let off the start position. Question: Is your engine failing to turn over at all on start up, or is it turning really slow in the start position? I too took a volt meter and read my batteries, and they were all fine...until I tried to start the engine. Then they acted dead b/c of the bad connection. I actually heard a "zzz-zzap" from the battery compartment with a little poof of faint smoke. One sure way I was able to determine this was feel all the the battery top post connections. I found one that was HOT, and taking off the wire discovered it was terribly corroded, thus the short in the connection. In fact, it got so hot that it melted the plastic battery casing around the terminal and the terminal actually FELL OUT. Of course, then I had to replace the battery. If you have a helper, have them look for sparks, clicks, pops, whatever from the back when you're trying to start it. If your problem is similar to the one I had, then feel the battery to see if one connection is hot. Besides that, possible a starter getting weak?? Again, please be specific on whether or not your engine turns slow and then starts, or whether or not it turns over at all and then fires right up. And I'm assuming you have an electric starter. I also had a old bus with an air starter that would hesitate b/c of a bad air solenoid.

Steve:
Thanks for the information. When the engine tries to turn over, it turns very slow. I felt the battery connections to see if they were tight, which they seemed to be, but I didn't notice if any one of them was hot. I did notice that there was more corrosion around the back of the battery box than what should be normal. I'll go back and check to see if it's a bad connection and take a helper with me to watch the batteries while I start it. Thanks again!
