rewiring UHF and Cel-Fi

[ninchi]

Need an adult to check my wiring. Currently setup like this and it works, but I have a cig plug dangling off the dash when the UHF and Cel-Fi aren't powered, and I can't power them independently if I have one or the other antennas removed.

The UHF was supplied with a 10A fuse, and the Cel-Fi is currently piggybacking off it.

Plan is to rewire like this:

191251

That removes the dangly cig plug, and allows me to switch them independently. The switches are 20A rated. Thoughts?

Looks OK to me but I'm a long retired electronics tech. Fusing is overkill but OK. The switches are more than adequate.

Getting rid of the cigarette socket/plug is a good idea.

Fusing is overkill but OK.

Agree. If it were me (and it isn't) I'd put a single 10A fuse at the battery end and make sure all the cabling and switchgear is good for > 10A. Remember the fuse is only there to protect the wiring.

Oh, the big difference between what you had and what you've drawn is what you had will power down the gear when the car is off. What you've drawn leaves open the possibility of forgetting to turns something off and winding up failing to proceed. Otherwise what Ron said.

Thanks both.

Understood, though these would run off the secondary battery which is protected by a Redarc VSR from discharging the main.

The smart move would be to connect it to a second battery, protected by a Traxide (or similar but inferior) isolator.
