Electrical question

sorry if this is in the wrong place... but that 12v ign thread made me think of something.


I haven't done headlight relays yet, but more and more I see "Relay" mentioned in electrical threads. And, I'm about running out of terminals, what with my electric water pump, choke, fans, aftermarket heater, stereo, remote start, seat warmers, yada yada yada...

If I have to add a new fuse block (5 or 10 terminals) would it be acceptable to use a relay from my "ign fused" or "unfused" on my original fuse block to the new fuse block?

I have a high output alt (80-90 amps at idle) and a deep cycle battery. all wires and grounds are new, thick gauge, quality copper, with weather proof connections.

I don't think I would. I would run a separate wire from the battery or the Bat terminal on the solenoid for it. Maybe someone else has a better way to do it. If so I hope they post it up....

that would work for a non-ignition hot... like to a painless switch panel, but I want a lot of things to come on when the truck starts and runs, and I don't want to have to find some place for a 10 rocker switch panel.

Re: Electrical question

Use ignition fused to turn on the relay, power it from the battery, run your new fuse block off the relay.

Re: Electrical question

you shouldn't need that much relay for a fuse box. a normal BOSH unit should do for most loads.

Re: Electrical question

already needing to be on another block:

heated seats: 30-40 amps
5000cfm fans: up to 30 amps
electric fuel pump: 15 amps

I'm letting my original fuse block just handle my ignition, remote start, heater, and the relays to my water pump and lights. I really don't want to chance anything about my electric water pump. These things aren't tried and true for daily drivers, so I'll spend the coin on a nice relay and fuse bock. They'll travel well, too
