When this happens, I can not turn the engine with the key. I replaced the ignition key set and the starter is not too old. Please help.

There are three possibilities. We are the contacts of the switch keys are wet from rain. Often, on the fly "bridge" if the lid is not sealing it. Secondly, there is a defective relay, so that it keeps the solenoid engaged, even when the button is released early. (I think that is the cause of your problem) and the third, the starter solenoid does not come off. If you use a lamp. Check the back of the switch. You will have a purple IGN. wire, a yellow or orange START position, and a red terminal of the battery. Turn the switch ON, power is at IGN. but not the terminal S. Click Start, and you should get the power to the terminal S.. Jump off, and you should not be able to S. If you go over. Big terminals on each side. Yellow with a small terminal. Turn to start. Power to S terminal and start eng. Turn the key to execution, if the engine is started check terminal. If the power. It may be relay or starter switch. If no power there, his starter. Good luck!

poor start

the solenoid is stuck on the starter or the starter before. Make sure the son is connected right to the small post on the solenoid.

a single thread.

you may need a heavy duty solenoid
