This solenoid was ordered from a tractor supply and the box is labled NCA 11450A(the correct number for an NAA) and 1100-0216 and has only one small terminal. If it starts with the push button there must be some way to wire it to work from the starter switch.|
The power to activate the coil is picked up internal to the solenoid from one of the 2 large terminals.........connect battery to wrong large terminal & it will not activate. If those 2 cables are wrong/reversed, a voltmeter at the small terminal will show nothing. If correct, voltmeter will show battery voltage.
Royce already said same, but I am emphasizing it. This post was edited by JMOR at 13:14:13 09/22/13.
