Radio voltage supply

Scotch 88 and self-fusing tape.

Throwing money around?

If it’s not as good or better than a factory-installed harness (materials, construction, routing, securement) then it has no business being in a commercial vehicle. Or my private vehicle.

And if better suppliers offer such that the install can go faster, with fewer problems, that’s value.

One needs be sure he understand the risks. Too many installs I’ve seen rely on dumb luck.

Voltage drop is a legitimate concern. How important he will figure. Loss of performance may be debatable, but a hot wire getting hotter & hotter isn’t.


Craig is like a lot of us. Dog-with-a-bone.

You probably misunderstood my post, which was my fault. I was trying to explain that Craig can’t worry about 2/10 of a volt loss, when the alternators not supplying 14.4 volts to start with. If the alternator is putting up around 15 Volts, that usually indicates a problem somewhere is the electrical system. I guess until Craig takes the voltage readings with a voltmeter and reports back, it’s just a guessing game at this point. That’s why I said it’s not worth throwing money at a problem, that’s probably not a problem to start with.

 

You say the voltage drop is a legitimate concern and I don’t disagree with that, if the voltage drop is high. A couple tenths isn’t that big a deal, in fact you might be surprised that it’s normal with most radio systems.

If the power wire is getting hot, then yes you need to use a heavier gauge wire. If it’s fused properly, the fuse should blow before the wire ever gets too hot. Since that’s the purpose of a fuse to prevent fires and protect your radio, and vechicle, etc.

Far as the bone goes, I think a certain tech has fed you a big enough bone, that’s made you guys nervous about your radio systems. I’m not saying any of this as a put down. I just hate to see you guys keep throwing money at something that probably isn’t even a problem.

 

Ouch ... certain tech .... tooooo funny!

 

I'm trying to figure out what you are doing.

By the way the volt meter is what the ecm sees, it is a multiplexed gauge.

 

I like to use undersize wire like say 28 gauge, then I wrap it tightly around the inside if my Big Gulp, cover it with heat transfer compound fill with ice often, this way I get maximum usage of the heat generated when I key up my Henry amp.

 

Nothing to discuss until that's done.

See step number one above. It only takes 30 seconds of your time.
