The Stupid Electronics Questions Thread

Since mine is a vortec, it has 2 positive cables ( the shorter one goes to the starter and it has the smaller wire to the alternator, and the looooong one goes across the fan shroud and down the driver's side inner fender to the back of the PCM). That one is 8 feet long, and was corroded inside. The parts store wanted over $100 for a factory style replacement, and it would have to be shipped from out of state. Found a battery/electrical shop on the other side of Houston that could make me one, with regular cable lugs, for $11. And in about half an hour no less! So that's what I used, and cleaned up the other cables.

I converted mine to top post with my 34/78 battery and used these.

Or you could use a couple of these for your side terminals.

I use a side terminal bolt on positive side to mount my winch cable to. Works great.

How is everyone coming thru the passenger side of the firewall with accessory power wire?

I have an 8gauge wire I need to run for my little slim powered sub under the passenger seat and not sure how to bring it thru the firewall from the battery. All on the passenger side.

I just drilled a hole beside the hole for the antenna, passed the cable through a grommet, then I siliconed the hole to seal.

Saw you post this is another thread. I like the idea but that's still a new hole in the firewall

There's really no way around a new hole in the firewall lol.

I just like that it's not going to vibrate and cut itself on the sheetmetal like a firewall grommet. My Jaguar had similar pass-throughs from the factory.

The sound on my 98 Suburban is cutting out. Timing varies from mostly working and occasionally cutting out to mostly silent and occasional sound. I’m suspecting it’s a loose connection or bad speaker wire. Are there any spots to check first? Any known wear areas? Or does having all sound cut out narrow it down at all?

I would check the speaker wires. I know over time they get a bad connection
