Alternative use for glowplug resistor?

[FrankenCub]

I have some radio equipment going in my M1008 and was wondering if I could use a glowplug resistor to get power for the equipment as a way to bypass adding additional stress on the front battery. At least this way it would be drawing from both and I could run it to a fuse panel just for the radios.
But, with concerns of glowplugs having a cascading failure when one goes, would there be a risk of the radios getting too much voltage for some reason?

To use a resistor to reduce voltage, it must be sized correctly for the load.

No, you can't use it for what you asked.

Best way to do what you want is to get a 24v to 12v converter.

Or just run it off the front battery. It's not that big a deal unless you are planning to use a serious amplifier.

Thanks guys. I may look into converters just so I can keep to load spread between the two batteries. I realize that running off the front will also work but at night running lights plus my radios will just keep one alternator working more. I may not see a problem over a few years but I think it's still best to keep an equal load as possible.

Ive run my equipment (two way radios) off the front battery for 16 years. Other than normal battery replacements its worked fine. Finally rebuilt the drivers side alternator this year to get rid of a RF whine, but it was always worked A-OK. YMMV

Well I suppose I shouldn't worry about it too much, maybe I'm just over thinking the whole bit.
I have a dual band Icom in now, a modded Yaesu and a simple Cobra CB going in, and a laptop that I'm building a mount for. The things you get involved in when a group of similar thinking guys (and gals) get together lol.

I think so. There are quite a few people on here who run a bunch of extra 12v stuff. They seem to do okay.
