CJ Headlights - Passenger Bright, Drivers Dim?
OK - 1983 CJ7, essentailly stock as least in terms of the electrical &
wiring. I took the grill and radiator out recently while replacing on the PS gearbox which meant disconnecting headlights, turn signals and etc and pulling the front harness. All of the lights (headlights, turn signal and etc) were working correctly before working on it. But when I re-installed everything, the drivers headlight is very dim (VERY dim) and the passenger headlight is pretty normal brightness. Turn signals work as well as before --- that is to sday , they work good. The harness was left connected to the bulkhead connector while I was working on the Jeep - which still starts and runs like it should I'm thinking a bad or loose ground, but can't see any loose wires or ?? Any suggestions on where to start? Diagnostics? Haven't tried swapping bulbs side-to-side yet - but will when I get back into the shop. Thanks Lynn in Vancouver WA |

Re: CJ Headlights - Passenger Bright, Drivers Dim?
Step by step? A) Swap the headlamp bulbs and see if the problem travels with the bulb. This would also be a good time to upgrade to a new set of Wagner Tru-View lamps, you will be amazed how much better they are than stock plus they don't overload the stock wiring and switch! B) If "A" didn't do the trick, take a Digital Multimeter (voltmeter) and check the voltage at each headlight connector. Be sure to turn on the lights and don't forget to switch them from "DIM" to "BRIGHT" and check both circuits. Should be almost the same as checking between the battery posts, without the engine running around 12.3 to 12.6 volts. If they check good voltage, check the resistance of the Ground Circuit of the headllight connector using the "Ohm meter" feature of the Multimeter, it should be virtually "0.00". Sometimes each headlamp has it's own ground circuit, you may have loosened one during your mechanical adventure so trace the ground wires to see what you have. Good luck, Bruce |

Re: CJ Headlights - Passenger Bright, Drivers Dim?
Swap the bulbs first of course. Then dig out an ANALOG multimeter, much
better at finding intermittant problems and diagnostic work. The easy way is to turn on the headlights, see the dim bulb. Check the voltage to a good ground (battery terminal if possible) on BOTH sides of the bulb with the lights on. A good system will read 12 volts or a bit less on one side, 0 volts or a bit more on the ground side, 10 to 11 volts across the terminals. If you get less than 10 volts on the high side, start looking for a bad terminal block or frayed wire. If you get several votlts on the low side, bad ground. The bad ground can either be on the wire from the socket to the body or the ground strap from the body (on the firewall) to the back of the engine Highcountry wrote: > Step by step? > > A) Swap the headlamp bulbs and see if the problem travels with the > bulb.

Re: CJ Headlights - Passenger Bright, Drivers Dim?
Assuming the lamp itself is good it appears that you have a circuit
grounding problem. You will need to get in there and manually clean (and coat with dielectric grease) the ground connectors and connections. Perhaps another Jeeper can give a specific locations to check, I'll just say take apart and clean every connection you can find. FWIW.... I had a '68 Rambler American with the same problem which occurred at some very inopportune time so I temporarily added an additional ground to the circuit by tinning both ends of a section of 14g house wiring and using it as a jumper from the ground side of the dim headlight to a bolt on the grill. I drove that Rambler for a number of years before giving it to my baby sister who drove it until 1986...... with that temporary fix still doing its job!

The ground tags for the headlights are on the back of the grill. I
would be thinking one of these wires got damaged or is loose. Or a loose plug on the back of the light...

Re: CJ Headlights - Passenger Bright, Drivers Dim?
CJ headlights are individually grounded via a pair of #10 screws and nuts, one on each side of the back panel of the grill, 1" below the center screw hole for the cold air induction flange (on the left, and the same space on the right). You have to pull the headlight bucket to see the actual connection. They just serve the headlights, the parking/signal lights use the sheet metal for the ground path and have no seperate ground wire.

Re: CJ Headlights - Passenger Bright, Drivers Dim?
Just a note: Users should be careful about metering problems like this without the proper load attached. A crappy ground connection can let you read full voltage at no load (leading you to think that it is OK), but the voltage evaporates when you plug the lamp back in.
