Headlights don't work: fuse or circuit breaker 84 Chieftain?

[Gazoo]

I recently bought an 84 Chieftain and cannot get the headlights to work.  The tail, brake and clearance lights work properly.  I thought I had it fixed when I found the headlight switch held together with about 10 feet of electrical tape but a new switch did not fix the problem.  I have checked both headlights with an external battery and jumper wires and they both light up just fine. I looked on the fuse panel and found fuses for everything but the headlights.

Does anyone know if there is a headlight fuse or circuit breaker for this circuit?  I am new to this RV and do not know what chassis it is on and have not had any luck finding any electrical diagrams available for it online.

Thanks in advance for any/all help!

Hi  Its most likely that it is on a P30 Chassis  and fuse panels are a problem.  Also dimmer switch could be at fault, There has to be a fused curcuit. any Chev wireing diagram should put you on the right path. Frank

For that year the Power Center will most likely be either in a cabinet or under the bed.

Edit: Opps, maybe I better slow down and read closer.  What Rick said below.

Is your shore power cord plugged into the generator? Mine has an outlet for the generator that the shore power plugs into.

Just went through this with mt 76 superior checked wiring fuses everything finally tracked it to a shot dimmer switch!!! I had every symptom u have all lights worked except headlights

I think Rick has got it.


Should be a box inside your cable (shore line) storage to plug into to get Gen power to the coach.

If one of the AC's are working when the genny is running, but nothing else, you must have a breaker tripped I would think? My 86' has the AC/DC convertor with 12v breakers/automatic transfer switch/and AC breaker's all in one unit mounted back near the rear of the coach. Maybe yours is similar i??

[Rickf1985]

If one A/C will run on the generator with the shore power unplugged then you have other issues as far as the rest of the outlets. Most of these units will only run one or the other AC but not both on the generator. There might be a switch near the DC power center for front or rear AC. Unless someone has added an automatic transfer switch then you have to do something manually to get generator power to the coach.

If your gen is not a least a 6.5KW it's not going to be wired to run both AC.

[legomybago]

30 amp service will only run 1 AC

50 amp service will run 2 AC's

Its all a mystery at this point!!  W%

Quick way to check.
If your gen has 2 circuit breakers, one of those is for the other AC.
