reverse lights
 

my truck keeps poping the 10amp fuse for reverse. it doesnt pop it right away though, takes about a week. any ideas of where to look?

Start at the bulbs, then work your way to the fuse box.

Between the fuse and reverse lights is a switch in your transmission. When the shift linkage goes into R, it allows power to run back to the light bulbs. Somewhere along the way you have a short.

ive changed the bulbs, and redid the trailer mate harness blocks, they were all corroded. so idt my problem is there, in the day light tommorrow if its not raining ill start to follow the wires off the reverse switch in trans. is it possible that the switch is bad, and which plug is it on the trans?

This should help....Post #6

thats for a 5spd, i have a slushbox.

It is going to be the neutral safety switch which controls the reverse lights.

i just looked with the flash light, theres 3 plugs from what i could see the one furthest to the back with 2 wires seems like it would be the reverse one. im going to follow it up tommorrow.

Rite on. :pca1:

ok mint. if everything checks out good, then where should i look? also seeing where the switch is just completing a circuit, i dont see how it could go bad. if it had multiple wires then i would say it could be sending a bad signal. if that makes sense.

Use a multi-meter and do some testing. See what the current draw, voltage and resistance is along with continuity from the fuse to the bulb. That is about all I can tell you. Maybe someone else will chime in and provide more for you. :c:

This is for a 2001 47RE, but it should be very similar:

I'd set you meter to measure continuity, and have the alarm on. Unplug the fuse and bulbs. Plug the meter in where the fuse came out of on the "cold" side. Put the other end to ground. From their, wiggle the entire harness from the fuse box to the reverse switch. If it goes off, you have short to ground between the fuse box and B/U switch. Put the truck in reverse, engine off of course, and wiggle the wires between the B/U switch and the tail lights. You should be able to find out if you have a short to ground or not doing this.

Also, check for continuity between the B/U switch body, and the terminals in it.

speaking of witch where is the neutral saftey swith at I have a no lights on my truck and want to fix it Im tired off pulling out the flashlight to see behind me..

did not mean to steal your thread sorry!
