Pyrometer - ttikalsky - 06-26-2006 04:11 Replaced the probe still no reading at the gauge, any suggestions. The guage is an ISSPro pyrometer/turbo boost combination and the turbo boost guage works. Troy 1986 Newell Pyrometer - Leroy Eckert - 06-26-2006 15:19 When the problem happened in my coach I replaced the probe only to find that the wire was not attached at the guage. Worked fine after the wire was attached.

I searched the archives and there was mention of testing the guage posts for 4 ohms without the wires, guess I will try this test also.

I have ab '88 WLWB with a detroit diesel 8v92. the pyrometer guage does not seem to be running at the correct temp. I got earl to send me a new sending unit. The new sending unit has two wires on it and the unit that is presently installed has only one. I was wondering wheather anyone has any information on this.

The reading is not absolute but imperical in that is a referrence temperature reading unless the connecting wires are taken into account in calibration. There has to be a return path whether it be the frame ground or by wire. Using a wire for a return path would give greater accuracy to the reading. Possible the reason for supplying a 2 wire instead of one? At your meter find where one wire went to ground, connect one here the other to the other side of the meter. Polarity has to be observed, so it you have connected backwards the meter should delfect downscale, if so, reverse connections. Maybe your original pyrometer is not bad, just a bad ground? Run a wire from a good ground at the thermocouple to the point mentioned above. My best guess on the subject, maybe someone who has changed one will jump in here. bob janes, '87fc35, greenville, sc --- In WanderlodgeForum@yahoogroups.com, jim riordan wrote: > > I could use some help.

I bought it from a local Blue Bird Dealer. My old one only had one wire too. The new one had two wires which one was a ground. The parts man said that the old one was grounded to the rad & I wouldn't need to ground the new one. But he also said that wouldn't hurt to use the the wire to ground it also. I used the ground wire as you can't have it grounded to good. Don 89 Sp 36' Butler, PA Bob, Thanks! When I observe the sending unit that is installed now there is only one wire that comes out of the unit. the replacement that I got from Earl has two. Your point about a ground is a good point, i think probally that the ground is already achived by it's mounting though.

Is the length of wire predetermined on this gauge? Bill 84 FC 35 SB "$quanderlodge" Terrace, B.C. Canada Looking for the perfect gift? Give the gift of Flickr! Pyrometer - Donald Watson - 02-04-2009 10:01 Bill, The wire length should not be predetermined as far as I know. The thermocouple acts as a probe and produces a small signal measured in millivolts, sometimes amplified depending on the pyrometer gauge circuitry. Obviously, sound electrical connections are important.
