fiberglass tub and taillights

I grounded the plate in the housing to the frame and got left turn and running lights on both, but no right turn, brake or backup lights. What am i missing?

Thanks in advance
Dave

You grounded both light housings? Make sure the b/u lights are plugged in on transmission and by bulkhead connector, and maybe check that the bulbs are still ok.

Yes both lights are grounded to the frame. I got reverse lights to work (fuse). Everything on the left side started working fine but i cant explain why. I pulled the bulbs out and used my meter to check for voltage and i get 12v in all scenarios on both lights but there must not be enough current to light the right bulbs. If i take both grounds off everything works but its very dim. So i fiddled grounds and couldnt make any progress. I cut the trailer light harness out and respliced the right hand light into the harness ahead of its original connection at the left hand light plug and still no changes? Do i have a bad bulkhead connector or fuse block? All this worked before the glass tub swap.

Found another flasher in my parts bin, still same problems. It must be grounding back through other circuits when i take the grounds off, but atleast i know the wires are good. When i ground one or both lights the driverside works fine but the pass side only gets reverse and running light. Take all grounds off and everything works but its very dim. I hate jeeps! Once this one is finished its going back to its original owner and i hope to never have another one in my garage.

So you have power for brake/turn but no light lighting? Have you tried a different bulb? Did you install the bulb correctly? I know they have asymmetric posts to help put them in right, but they can at times still be put in backwards..

Yes i checked the bulbs. Even swapped the whole light housing. I have voltage just no current. I think its something in the harness or maybe the column, i just hope i dont have to take the column out again

Hate to say it but usually voltage but no current is a bad ground.... someplace..

Check the ground at the tail light with a VOLTMETER. if you have any voltage on ground, then you have a bad ground.

Ground meter at battery for this test.

I checked grounds and even grounded the lights back to the battery. I just pulled the column harness connection apart and it all tested ok. Shot it with WD40 and now the lights work... must have been a culprit of the water leaks this thing has had since it was new. I have to rhino line the interior hang the tire carrier, new shift boots, and new cowl gasket then it goes home... finally. This will be my last jeep frp body swap, and hopefully the last cj i have go through here. That said many thanks to this forum and the great people who have more patience and knowledge about these seemingly simple quaint yet menacing vehicles.
