Default Dim Headlights

On my maiden trip In my 87 PT. Got caught after dark on the way here, and the headlights were very dim. Checked the voltage at the socket, and only had 8.9 volts. This while on shore power, and the batteries showing 13.8
I hope to upgrade the headlights to LEDs and control them with relays, but not now while on the road.
I've searched WOG for a wiring diagram, hoping to find and clean up a bad connection or two.
All suggestions greatly appreciated..
Thanks,

The headlight switch is responsible for almost all of that voltage drop. I would suggest just installing a relay first and going from there. You also need to put circuit protection on the power to the relay, I suggest a breaker and not a fuse.

Beware the LED lights, most of them seem uber bright when you stare at them, but aren't very good on the road. Maybe someone here has some experience with a good one that I haven't, have to wait for that advice. But start with the relay and see how you like it.

If you can't find a wiring diagram I'll whip one up real quick for you.

Thanks Andy. Wasn't really sure about the LEDs, but I definitely want to make an improvement. I'm out in the boonies, and can't affect proper upgrades, but I spoz rigging a temp relay could work.
Was hoping to make repairs to the existing to get me back home.

The only part you can "replace" to make it better is the headlight switch in the dash, which you should actually be able to get at a good auto parts store. That will get you a couple volts for a while and brighten them up some.

The 2nd one is hard to read, but looks correct. The 3rd and 4th on the list do not have any circuit protection and should be DELETED. That is a fire hazard, especially since it's the single highest current draw of any 12v components. Fire hazard!

Thanks for the replies fellas! I'm going to do the relay upgrade as soon as I get back home. Will avoid night driving on this outing.

I did this upgrade this past summer and it made a huge difference. I used these relays:

https://www.amazon.com/PACK-AMP-Wate...KVH7XM56D964Q1

and these breakers:

https://www.amazon.com/ZOOKOTO-12-24...s%2C140&sr=8-9

My setup is a little overkill as I put a breaker and relay for each of the 4 headlights. I ran a 10awg wire from the battery bank.

Thanks Andy, I’m surprised that went unnoticed back when those drawings were first submitted! I’ll look into editing the 3rd and 4th drawings to at least include a note about the need for circuit protection.
