Default No headlights low or high beam, yellow running lights work

I just bought a 1986 Wanderlodge PT-40.
Unfortunately the headlights are not working.

first checked bulbs they are nwe and light up when connected to a battery ok lights good.

Bought a newswitch and installed same results

No headlights low or high beam, yellow running lights work and the **** headlight alarm works ok switch good.

Perhaps its the high beam switch or fuse found the dimmer switch but got dark and could not get a meter on it cleaned up and came inside

found you names in the user group and saw the relay upgrade also noticed a recall to replace 50 amp breakers with 105 amp breakers,,

Still trying to locate fuse/ breakers for lights any ideas.

Thanks

Dave,headlights never have fuses,the switch itself has a circuit breaker built in.
Most times when the dimmer switch goes bad it will work on high beams,the low side burns out most of the time.
But the dimmer switch could have the wires unhooked or a bad wire.

There will be a terminal block for all the headlight,tail light wires and turn lights,i'm not sure where that block is on the 86PT40.

Also,please complete your signature to include the year and model of your coach,that always helps when you have a problem or question.

Thanks Randy Im going to replae the dimmer switch next looks like the orange wire is burnt on the headlight switch. I triedto trace it but no luck. I williling to bet its the wire to the dimmer switch though. I may just rewire from the switch to the dimmer to be safe. Do you know if the bosh relays were installed on the 86, I found two under neath the drivers window panel Im going to replace them also just becuause Im there.

If nothing else i Can rewire the whole thing I got all weekend..
Thanks I will update my signature soon..

Hi Dave,

On the 84 ½ PT-36 that I had, the terminal strip was mounted near the top of the compartment that housed the generator battery. I attached a PDF of the terminal layout.

Default SWITCH AND DIMMER OK -BAD WIRE i THINK

JUST checked dimmer its ok but no power to the dimmer switch.

Went from battery to hot side of dimmer both low and high beams work.
Problem somewhere between switch and dimmer --- lot wires under that dash.


Question is the dimmer wired straight from the switch or does it go through any kind of junction/ckt brk???

I know I can fix it now just need to determine how to wire correctly ?

I will likely put a ckt/fuse between switch and dimmer switch and use 14 gauge wire should work if not then i will be scratching my head.

Anyone have any suggestions or ideas???

Thanks

NO FUSE ON HEADLIGHTS.
I would run a new wire from the headlight switch to the dimmer switch.
And I would do the healight relays to brighten the headlights,and that will take a load off the headlight switch and the dash wiring.

If you replace any relays make sure you use bosch or something just as good.
NAPA relays weigh half of what a bosch relay weighs,half the weight means half the copper.
maybe they are solid state,but I doubt it.

Dave,

The diagrams located on this Forum at http://www.wanderlodgeownersgroup.co...hassis%201.PDF and http://www.wanderlodgeownersgroup.co...hassis%202.PDF may help.

Got them to work!!!
Installed a flip switch for headlights and yellow parking lights and ran a new wire to the dimmer switch..
Bought relays to install but to hot in Mississippi to playing outside. I will wait until I get to California where the weather is a little cooler. I will take some pictures and wiring diagram in case someone needs it later.

Thanks for the help..
