Fun with Electricity, PO Stuff #5 in the series, or is it #6? Options

Going to RRC2023 last week, I lost all my gauges just after leaving home. Pulled over to check things out and found a blown fuse. Blew a couple more before I figured out it was the left turn signal. Didn't use them for the rest of the weekend. I asked around and someone suggested I check the flasher or turn signal relay. I dropped the fuse panel and found this. Did someone swap my relays around?


More in this thread to follow. I found lots of crap...

Car is a 74, but... it has a Gates dash conversion and I don't know anything about the gauges, if they are 911 or 914, could be some of each. I will have to take one or two out soon to answer some other questions anyway. I don't recall if the indicators ever worked separately or not.

I do have the EP26 that I purchased from you, 2 actually. I was going to do the LED upgrade on 2 cars if the first one went well. So much for that. I am going to put the 2nd relay in just for another test comparison. @Spoke do you do any mods to the EP26 or are they all the same?

It looks like 3 options at this point;
The switch, looking for a spare to test
The relay, easy to test since I have another
The LED bulbs, I could try another set

I have seen info on adding a load resister to non LED circuits. Is that in play here?

Sounds like you do have funky things going on with your lights. If LEDs didn't work in the front but incandescents do, then it might mean the ground is not making contact in the front. Check to see if both filaments light up with turnsignals. Do the running lights work with bulbs and LEDs?
EP26 from me are modded for early tachs with separate L and R indicators and for later tachs with a single R/L indicator. The EP26 mod has to match the tach type.

The load resistor thing is for cars using LEDs with OEM flasher relays designed for incandescent bulbs. Not needed on your 914. You should be fine with EP26 as it can drive LEDs or incandescents.
