If the gauge starts to climb towards full, then the gauge & wiring to it are probably OK. Probably best to not leave it this way for long, but a few minutes won’t hurt.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">My next suspect (especially since it worked before restoration) would be the grounding for the sender. IIRC the TR4 grounds the same as TR3, meaning not very well. I like to add a ground wire from the stud on the sender to one of the tank mounting bolts.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Use an ohmmeter to check the sender. I don’t recall the exact numbers offhand, but it’s something like 100 ohms empty and 10 ohms full. If it seems to work backwards (low resistance empty and high resistance full), you’ve got a TR3 sender instead of TR4.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Also worth checking the temp gauge if the first test above doesn’t work. Do the same thing, pull the wire off the sender and ground it. If temp gauge doesn’t respond either, it’s probably the voltage stabilizer. Seems like maybe it’s mounted over in the passenger footwell on a TR4, but honestly I don’t recall for sure.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">-- Randall<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Sent from <a href="https://go.microsoft.com/fwlink/?LinkId=550986" target="_blank">Mail</a> for Windows 10<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><div style="border-right:none;border-bottom:none;border-left:none;border-top:1pt solid rgb(225,225,225);padding:3pt 0in 0in"><p class="MsoNormal"><b>From: </b><a href="mailto:trguy75@gmail.com" target="_blank">Jim Henningsen</a><br><b>Sent: </b>Saturday, August 17, 2019 6:54 PM<br><b>To: </b><a href="mailto:triumphs@autox.team.net" target="_blank">'Triumphs'</a><br><b>Subject: </b>[TR] Fuel gauge troubles<u></u><u></u></p></div><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Help, I'm calling the TR bat phone again.
