Vicki B Posted May 8, 2023 Share Posted May 8, 2023 I have a 1987 Nissan Mini Cruiser. My rear brake/blinkers work but running lights do not. I've checked fuses and replaced bulbs, where do I go from here? Vicki B Quote Link to comment Share on other sites More sharing options...
extech Posted May 8, 2023 Share Posted May 8, 2023 do the marker lights on the top front and rear work? Quote Link to comment Share on other sites More sharing options...
Vicki B Posted May 9, 2023 Author Share Posted May 9, 2023 They do on the front which have been replaced with new led(?) Rear do not. That is what I'm trying to get working Quote Link to comment Share on other sites More sharing options...
Maineah Posted May 9, 2023 Share Posted May 9, 2023 You most likely will have to add a resister to the led circuit. Quote Link to comment Share on other sites More sharing options...

I thought that ^ was needed just to get older-style flashers to work (i.e. turn signals) - ? Vicki, do you have any actual voltage at any of the wiring or contacts for the rear running lights? That's where I'd probably start, with a meter—any cheapo unit will work. Quote Link to comment Share on other sites More sharing options...
extech Posted May 9, 2023 Share Posted May 9, 2023 i think you are getting good info. no resistor needed tho. believe power for the front marker lights comes from the rear, so its likely at the rear lights (the prob) a test light is all you need, pay attention to grounds Quote Link to comment Share on other sites More sharing options...
Maineah Posted May 10, 2023 Share Posted May 10, 2023 Flashers etc need resistance to work, the LED's provide little or nothing this is why you have to provide resistance. The bulbs in the original set up have enough resistance. The marker tail/ lamps are not part of the scenario so the problem is not related.

REALLYRURAL Posted May 18, 2023 Share Posted May 18, 2023 Most likely you have a problem in the wiring underneath or a bad ground. Crawl underneath and look at the wiring harness. Bring a test light and figure out which wire is which. Pretty common situation and the wiring needs maintenance on these rigs. Quote Link to comment Share on other sites More sharing options...
