Warn power interrupt wiring advice (1 Viewer)

[RaleighCJ]

Hey guys,

Have a power interrupt kit on my truck with front and rear connections attached to two solenoids under the hood.

Trying to simplify wiring, have the switches to turn the solenoids on running thru a fuse block from the passenger side battery. Was thinking running 0ga wire through a distribution block that are usually used for amplifiers from the driver side battery to the solenoids. Would the distribution blocks hold up or would they end up being fire hazards? The power interrupt is used for a portable 6k winch and jump starting using warn jumper cables.

TIA

what brand 6k winch? how long is the rear run? what is the minimum run voltage for the winch? what is the max amp rating of the distribution block?

it would probably be ok but, you still want to make sure

example a 1/0 cable at 18' will drop about 0.7 volts. so you would actually only be supplying your winch with 11.3 V ( you need to calculate the wire running from the battery to the distribution block, to the rear to get the total length. or you could just measure the voltage at the end of the cable if it is already run.)
say a 1.9 HP motor pulled 196 amps at 12 volt. then at 11.3 volt it would pull about 209 amps in ideal conditions. If you have a weak ground to get a dirty connection the amp draw will increase as the voltage decreases.

I believe you are saying you wish to delete the power interrupt kit (if you're talking about those marine-type battery shutoff switches) and instead just put the solenoids on a switch. Yes? That's a good move. Clearly the way you turn on/off the solenoids is no huge deal since they require little current. The main power feed to the winch motor simply needs to be short and a big gauge to reduce voltage drop at the load.

Running separate cables from each batt to a distribution block gains little. A 5 foot 1 GA cable carrying 200 amps has a voltage drop of less than 2% .... so the loss electrons experience on their trip from one batt to the other (if that is how you have them connected) is minimal.

It is an old Warn m6000 I rebuilt.

The interupts are to the rear is about 20ft of cable, warn p#32963. The front is warn p#62132.

I am trying to limit the number of connections to the battery. I am wondering if I run one 0ga wire to distribution block then 2 short 2ga wires to the front solenoid and rear solenoid both mounted side by side under my hood. All the distribution blocks I see on amazon don’t have an amps spec. Referring to the connection to positive terminal of battery in pic below.

Again tia. Wiring is not my best thing.
