 |
|
So a couple of years ago my car was acting up. When I took it to my buddy to have him look at it he reached behind the motor and pulled out a completely bare wire. Anyways from then on my reverse lights have not worked. Anyone know where that wire starts and ends so I can replace it?
Thanks,

It runs from the positive side of the coil to the tranny switch. then from the switch to a Tee connector in the engine compartment and then to each tail light.

Not mine, it's from Speedy Jim's website.

So I just put it in reverse with the key on (motor not started) got underneith it and hit the switch with a test light. it said it wasn't getting power. Does the car have to be started in order to give the switch power? Also I found 2 wires connected to it, so I'm sure I'll have to chase the ends down.
Thanks

Just need to have the key in the "on" position. One of the wires on the transmission is coming from the coil (via the bakelite fuse). Other wire is going to the backup lights (via a t-connector).
Turn the key to the "on" position (not start). Check for 12VDC at the following locations.
1) Bakelite fuse (both ends)
2) Transmission switch (both contacts) Make sure shifter is in reverse
3) Either one of the blue wires in the T4 connector
You can also remove both wires on the transmission switch and check for continuity on the switch (between contacts) with shifter in and out of reverse. Should be 0 ohms (short) when in reverse, Infinity (open) out of reverse. Do not have to have car on or start. In fact, keep key in pocket

| Reviving an old thread here. Has anyone been able to replace the BU switch without removing the tranny? |

| I personally did not do it, but a guy that I had working on my Thing replaced it without taking out the trans. It should be very reachable. |
