im messing more and more with limos.... and my new challenge is solenoid wiring... i have never been into solenoids but now it seems i must!

ill take pics if you guys think you can help.

Power in, power out, ground, switched lead. Simple as that.

so what is the main focus of having solenoids?..... to turn off everything on the out side?

For battery isolation, it's simply as it states. For motor control, it's to handle the high current and inrush that the motor leads and brushes cannot handle. It's just a large relay.

thats what i use.

It's a switch.

When it is switched off, (no 12v power source such as ignition), anything that is wired before and after it is isolated from each other.

So in my instance-

My stock batt up front is isolated from my 3 batts in the rear.

When it gets a 12v power source to turn on, everything wired before and after it is seen together.

For batts, it is to allow the alternator to charge all batts at once.

the terminals up top can be wired in almost any order so i'll break it down for ya.

You got 2 large posts and 2 small posts.

The 2 large posts are power in, power out. Either one is in and out.

The 2 small posts are 12v turn on via ignition and the other is ground. Again, anyone of those 2 that you choose can either be turn on, or ground.

When wiring in series and\or parallel, each solenoid is independent so you can always choose with pair of posts shoudl be used for whatever purpose.

Some also have an accessory terminal as well. This will be powered by either the hot or switched side.

thanks guys... im gonna need alot of help so please just walk with me....

i need to get this stright.......

[jonbearsmt 919]

lemme ask anyone this..... in this pic... what are the yellow links for.... should thay even be? if what im understanding is correct the input on the right is opened and shut by either a ground switch or a hot switch.. (one of the small post) to let the flow go out the post on the left .. the out if you will... is this correct?

I have no idea why they are there but they look like diodes. Diodes only allow current to flow one way.

Could you explain when each terminals wires might possibly go?
