Hey guys I’ve reached out before about my truck I’m still having issues with it sadly. Bit of a backstory the MM was driving really well I replaced the carb and installed a aftermarket Weber. I just installed a new head unit and 4 way speakers in it. Everything was fine for a week or so after then one day I parked it and it won’t do anything with the key in the ignition. I checked my fuses and I checked the battery. I was told on here about fuse links off the battery but I can’t find them it seems my battery only has the positive cable running off it straight to the starter. I would appreciate some more advice cause this truck is my daily it’s really hurting me just sitting parked. Thank you!
