I'm trying to figure out a weird problem with my 1978 FJ40's cigarette lighter. Electronics are definitely not my strong suit.
My brother (@BRShap) and I bought our first 40 last week, and I'll post a thread about our road trip bringing it back to NY from Alabama soon. Truck is in great shape, but we can't get the cig lighter to work, and it won't work with a USB charging adapter.
Our first though was a blow fuse, so we used a multimeter to test the fuse and it isn't blown. Next we looked under the dash and pulled out the ashtray for better access, and found that the red wire with a black stripe and bullet connector was loose. The other white wire was attached. We figured that was the problem and connect the bullet, but lighter still did not work.
I then used the multimeter to test the outlet, and MM detected some voltage, so I know there's power going to the outlet. This has me pretty stumped. If current is flowing, why isn't the lighter or USB charger working.
All I can think now is that the whole unit is somehow damaged and needs to be replaced. I don't see any signs of rust or dirt, but haven't pulled it all out yet.
Do you guys have any idea of what's going on? I've searched the forum, but haven't found the same problem.
