TR6 TR6 blower motor and fuel gauge won't work

Greetings! New to this site. Just bought my 3rd TR6 and working on fixing the little TLC things the previous owner didn't get around to fixing. I replaced the voltage stabilizer and blower motor switch and the fuel gauge and blower motor still don't work. Not sure if its related or not. The voltage stabilizer is new but purchased about 20+ years ago and never taken out of the package. All wires seem to be attached in the back and no fuses are blown. Suggestions???
 
What is the voltage at the stabilizer?? Should be 9volts. You have 2 circuits here, the blower is on a 12 volt line.
Odds are the plastic float in the sender is dead. Replace the sender if so.
Be aware that there are 6 different wiring schematics for Tr6's

Thank you I will! What do you mean by sender; fuel tank?
 
Start buy buying an inexpensive multimeter and downloading a wiring diagram. You can measure these things; no need to guess.
 
Checked the voltage; stabilizer is working/power to the temp sensor and sending unit in the gas tank. Looks like its the sending unit in the gas tank. Haven't chased down the blower motor issue yet.
 
Easiest way to test the sender unit is to just earth out the wire going to it, if the gauge goes up then its the sender or as mentioned the sender is not grounded, in which case add an extra ground from the sender unit body.

Thanks I'll try that!
 
My new to me ā€˜74 TR6ā€™s electrical system barely worked. I disassembled the fuse block and cleaned every connectionā€¦ night and day difference afterwards.
 
IMHO items such as a fuse block should be refreshed with new Lucas bits as a matter of course.
Just looks so much nicer/works. A bit of dielectric grease on the fuses will also help down the road .
