Off topic: Starter control circuit (solenoid)
Yahoo Message Number: 118416
This has nothing to do with LDs.  This is about automobile starters.
 Calling all automobile starter experts/tinkerers.  I need help with some basic (I think) info on starters (specifically a 97 Maxima starter, but I don't think it matters at all.)

So, there are three connectors on the starter:

- Ground (body of the starter).  No question on this "connector".
 - One big cable that is directly connected to the battery positive post. No question on this cable.
 - The other one is a small cable that activates the solenoid to close the circuit to turn the starter.  I know that when this cable is connected to the positive battery post, the starter will turn.  My question is how long can I keep the connection.  Will I ruin the solenoid if the connection is kept for more than 5 secs?  10 secs?  30 secs?
 The starter is not installed in the engine.  This is for learning/testing only.

Thanks guys.

That type solenoid is probably not designed for continuous duty. It may heat up if  connected too long, though 30 seconds shouldn't hurt it. I would be more concerned about running the starter with no load on it for that long.

When applying power to a starter that's not mounted to the chassis, be careful to secure it, e.g., in a bench vise. If you just hold it in your hand, the startup torque can cause it to twist right out of your grip. You could break your foot if that thing landed on it.
