That was some pretty nifty bulb troubleshooting. Way more than I did and yours was more scientific than mine for sure. By me wiring the brake light bulb, which is a higher wattage, to the turn signal circuit and getting them to work told me that I needed a bulb with more wattage in that socket...
The bulb I used was actually an 1156 not 1157 as I stated earlier. The 1157 is a two filament bulb and the socket for the turn signal is for a single filament bulb.
I just tried an 1156 bulb in the turn signal socket and it works perfect. These are after market tail lights. I should have mentioned that because there is a huge difference in them. As proof, I happen to have after market and OEM front lights. China vs Japan. The after market lights have a very...
I didn't have any more bulbs that fit the turn signal socket but I experimented by trying the hot turn signal wire to the taillight filament of the two filament bulb with same result. Then I tried the brake light filament and it worked. So I am thinking I need a higher wattage bulb that will fit...
Yes, it looks like the wire on the left middle is green/black and the right one is green/blue. The blue line is a little hard to see for sure but I'm pretty sure it is.
Yes, it looks like the wire on the left middle is green/black and the right one is green/blue but I'll get a better look at it tomorrow to be sure..
I was wondering the same thing about possibly the wrong turn signal.
Yes, I think the 78 schematic is a better match. Unfortunately the PO(s) have pretty much butchered the wiring and very little of it matches up with any schematic especially the rear harness.
I bought a 77 FJ40 about 18 months ago and have been trying to wring out some wiring issues. Most issues have been resolved. but one that I just can't figure out is the turn signals. Hazard works fine but turn signals not so much. When I select either left or right the flasher clicks once or...
