I have read a couple of threads on fuel gages but nothing came up with my problem.
I bought the TRUG in May, it was an electrical nightmare:
Gave up and pulled everything and started over, have everything working at that point, but I did not have the fuel gage working (new speedo and gage with 6K miles on it)
I pulled the sending unit and found the windings on it "blown out", okay.... no firey explosion and me flailing in the yard with my hair on fire...so it must have happened before I bought it.
Installed a new sending unit, turned on ignition, needle would not move. pulled and opened the vibrator...wires wrapped around the arm a blown out too....
Replace vibrator, turned on ignition, needle moves to 1/2 tank then drops.... check sending unit, good, check vibrator, good, pull gage and now the wire in there is blown....FFS! The battery is good, is there some type of resistor I am missing or something?
I am feeding power to the gage off the fuse block.
From my understanding...little as it may be, I have 12V to the vibrator, vibrator connects to gage, other wire on the right of the gage connects to sending unit....voila, so do I just go get a yard stick from the paint store and check it with that? ugh.... |

make sure ur sender and speedo both have good earths
the sender only earths thro the bolts into the fuel tank
i normally put a wire with a ring connecter under one of these and connect the other end to a good earth somewhere
often helps cos the sender doesnt always earth real well thro the tank |

that I do have, just like the picture. I was thinking I had wired it wrong, but everything I see shows that I have it correct.
Thanks, |
