Kohler Perkins - erniecarpet@... - 12-19-2008 07:33 Paul, from what I have heard, Bluebird is closed for the holidays.
Ernie Ekberg 83PT40 Wanderlodge Weatherford, Texas Kohler Perkins - Paul Downey - 12-19-2008 12:28 The water temp and oil pressure guages on my 83 PT35 are not reading correctly and i need to replace the sending units on both. I do not know if these were supplied by perkins,kohler,telflex or BB. I have tried calling BB tech service but get no return call. Has anyone replaced the sending units and if so have any numbers or where to purchase. Paul Downey Versailles Ky 83PT35 Our Rollin Home Kohler Perkins - Leroy Eckert - 12-19-2008 13:13
Kohler Perkins - Chuck Wheeler - 12-19-2008 13:40 Check the Teleflex site and see what the specifications are for the gauges. Then get resistors to and connect them in place of the sending units and see if the gauges read correctly. If not check the wiring and GROUNDS. I found a poor connection at the dash connector that caused both gauges to read incorrectly.

Paul Downey Versailles Ky 83PT35 Our Rollin Home Kohler Perkins - timvasqz - 12-19-2008 15:02 If you disconnect the sender wire and hook up a multimeter ohms 300 +to sender -to ground, the meter should show less ohms as the engine warms. If you know what the ohms value for 75degree and again for 150DegF you could compare it to your test and prove the sender. The temp gauge is nothing more than an ohm meter. I find it best to price the OEM sender and the gauge first. often you can find a more modern new pair(sender, gauge) for less than the cost to replace one or the other of the classic,OEM hard to find parts. the ohm value for the sender at a given degree has to match the gauge, they are a pair. one thing to look at is the scale . you dont need a gauge over 250 degrees and under 130 ( the wanderlodge 94,8v92 watertemp gauge is the worst example of a useful scale).. Some time the wire between the sender and gauge is screwed. if it is close, jump a wire and look to see if a hot engine moves the gauge any? dont use tefflon on a new sender. an idiot light is prompted by a switch not a sender, they look alike GregoryO'Connor ofTim&Greg 94ptCa --- In WanderlodgeForum@yahoogroups.com, "Paul Downey" > > The water temp and oil pressure guages on my 83 PT35 are not reading > correctly and i need to replace the sending units on both.

This is a good test of the sending unit and if the wiring is intact, but did not show my problem which was corrosion in the dash connector on the common return for the gauges. My first indication was when I disconnected the temperature gauge and the oil started reading closer to normal. That is when I used resistors in place of the sending units to provide a known reading. I first place the resistors at the gauges to observe their accuracy then at the sending unit locations which tells me what, if anything, is being lost in the wiring. The only reason I bring the up is I replaced a good gauge because a multimeter does not provide the low resistance load of the gauge and wiring or ground problems can be missed.

I understood it to be for the back light? I understand the 'to ignition' was +power to the gauge needel and the -end was a groundstrength to the needel from the sender.as the engine got warmer the grounding in the sender got better (less resistance or more contact) Is there a standard for a 'resistance value in ohms'per 'reading of temp' or are sender and gauge a matched pair? Is there a device that you can dial in a resistance value to check the performance of a gauge? I like your test method. our germination equipment require constant review.Review of gauges would be way better than waiting for at-temp peaks to check heater/dial accuracy This is Greg, I use Tims computer and password.

Tunrs out the problem was bad ground connections at the gauges. Earlier I even changed my main engine oil temp gauge. Later I found the gauge ok - a bad ground.

We have been on the road for the holidays and I wanted to beat the weather and did not take the time for email etc. We are in So far all the gauges in our Wanderlodge seem to follow the Teleflex standard. But they have more than one depending on the series. I have the information at home. I will look around the net the next few days or post it when we return home. I use an old Resistance Decade box I have when checking my gauges. It lets you dial in the desired resistance. Here is an example of one http://www.mcmelectronics.com/product/TENMA-72-7270-/72-7270 but I would not buy one. I have also used a 250 ohm and a 100 ohm rheostat to test the gauges by setting the resistance using a multimeter. - Chuck Wheeler-
