Ignition wire on solenoid

The ignition wire on the starter solenoid is burning up. I installed a aftermarket electric fan and when I hooked up the battery the wire fried. Can anyone help me.

Did you happen to connect wires from the fan to the starter solenoid by the battery??? If not where did you connect your wires for the fan?

The fan came with a control box, a positive and negative from the fan went into the box and a pos and neg went from the box to the battery

Did you see it smoking??? Those starters are known for those wire leads burning up.... It is real common I would try replacing the signal lead as far back as you can tell it is burnt.... It could also be a sign the starter is pulling to many amps

I did see it smoke, I followed I back and it went to a rubber housing with another wire coming out the same way and one smaller wire going in the other side, I replaced the burnt out wire and hooked up the battery and the same thing happened now nothing happens in the car ie: lights horn ect.

Re: Ignition wire on solenoid

You have a dead short somewhere and are in danger of burning up your car.
Disconnect the wires to the fan that you hooked up and put everything back as it was and see what happens.
You have no power because you either drained the battery, burned a wire up or blew some fuses.
Leave the battery disconnected when you are not checking or testing.

Pictures of the wiring would be helpful.

Re: Ignition wire on solenoid

Disconnect the fan from the solenoid, like stated above reconnect everything as normal. Next run the power wire for the fan through the fire wall and tap it into the factory fuse block, I have mine attached to the AC fuse since it is the largest. This will eliminate any extra load on the starter system.

Re: Ignition wire on solenoid

I wouldn't tap a fan power feed into any fuse in the factory fuse block.
Some fans can draw large amounts of current during start up and while running. As an example I know the SN95's had a 60 Amp fuse for the fan.

The power for a fan should come directly from the battery or a power distribution block, though a fuse, into a relay, out of the relay and into the fan motor. You hook your switch to the coil side of the relay, so there is not near as much current running through it.

Since I don't daily drive mine, this is working fine. It has been this way for several months now.

Maybe not now, but eventually you will burn something up.
Believe me, I know because I learned the hard way.

Thanks for the reply you guys, I found the problem, the ignition wire was shorting out. I traced a burnt wire to the firewall, replaced it and all was fine after.
