reverse lights question

...onto problem 35 of 10432 [img]images/graemlins/wink.gif[/img]
my reverse/backup lights do not turn on, i've checked the bulbs & for voltage to them with no luck, I've also checked the fuse box & that plug on top of the tranny (one right by the shifter) and so far I can't find anything wrong

...any thoughts?

Re: reverse lights question

The ground is connected at each bulb, check that but unlikely that both grounds are bad.

Power comes to the tail light harness through a couple of connectors. Would assume that since the wiring diagrams split up 1980 to 1983 and 1984 to 1986 (I have a 1983 and 1985 that are the same) you have a harness hanging down the passenger side, up against the firewall, it splits out to the transmission (backup) and the transfer case (4wd).

It's always a dirty connection (or just unplugged). Lol mine don't work on the CJ-7 right now.

Good Luck

Re: reverse lights question

yup, that was loose (one of the red lines was completly pulled out..but still no luck (however I now have voltage to the switch on the tranny...I closed that circit but still no luck; which leads me to believe its the wiring around the rear bumper (the rats nest of wires from a bad trailer wiring harness install is also a big clue [img]images/graemlins/wink.gif[/img]

thanks for the tip, that saved me hours

Re: reverse lights question

Guess you should be half way there... and quick too.

I hate when some club fist installs a trailer harness... still have some strangeness with the Scrambler that is ground related, but everything works. It takes some time to sort through. [img]images/graemlins/wall.gif[/img]

Re: reverse lights question

Just a note on the parking light circuit. If you have an electric choke, the choke and the manifold heater won't work if you blow the fuse for the backup light. So if your suddenly running rich all the time and stumbles when cold it could be your back up light fuse.

Seemed like a funny place to hook it up to but sent an hour trying to hook up my electric choke one night only to discover that the fuse was missing on my jeep.
