Bypass solenoid?

[hatcity]

I have electric to the boom on my truc for lites and boom extension.

lost all power, checked fuses, replaced solenoid.

Have power to sol, but no out. Can I bypass sol temporarily by putting power dircet to fuse panel?

Do sol. have a pos. and neg.? or power one side,any side and a ground.

sol. is 3 post continuous duty.

Thanks, Ed

Most common soleniods are either 3 or 4 post. The two big posts are the switched power(in/out not critical). If it has only one small post, that is the keyed postive to activate it(grounds through the bracket of soleniod).

Does it click when you activate the controls? Even if it does, the points might be burnt up and not make contact. If you can find a jumper wire, touch between the two big posts and see if something operates. Watch for large sparks depending on the current draw of the thing you are operating. If jumping the two post makes it work, then you need to replace the soleniod.
