When I went to hook up the solenoid I noticed the one wire from the key ignition was hooked to right side of solenoid. Every diagram I have looked at shows both wires from the key ignition running to the regulator. It seemed to be working fine, but could this be why I'm now replacing starter? I understand there are multiple ways to hook up the solenoid, I just want to make sure this way is acceptable. Thanks, Tim [Reply]   [No Email]

The 6V-starter motor does just fine on intermittent 12V starter duty. There is NO problem, connecting yer ignition ON switch to the right side of the 3-terminal starter solenoid as you described. Iff'n you connected to the left side of yer 3-terminal starter solenoid, yer engine would only run while pushing the BIG thumb starter button by the tranny shifter. Remember, yer 30-0-30 ammeter was originally wired for positive (+) ground and will read BASSACKWARD with negative (-) ground that yer 12V-alternator demands. Iff'n still the original "loop" ammeter, just thread the ammeter wire thru the loop the OTHER direction, otherwize swap leads on back of 2-terminal ammeter. Surprizingly enuff, ammeter don't care, positive (+) ...or... negative (-) ground and even more amazing don't care iff'n 6V or 12V. HOWSOMEVERS: both the original 6V-squarecan coil and the modern 12V-squarecan coil use the same "infamous ballast resistor".......NO ARGUE!!! ........Dell, a 12V advocate for the right reason, who knows 8-ways to convert to 12V and they all work the first time [Reply]  [No Email]

Left side is hooked to starter and small post in back is hooked to the push start button. Now all I gotta do is charge the battery and I should be good to go.... Thanks again. Tim [Reply]  [No Email]

I got everything hooked up to the new solenoid and starter, everything seemed to be correct when I connected the battery. No sparks or engine trying to start before I hit the button, but unfortunately when I did hit the button all I got was a click. The battery is less than a month old, put it on a charger and it doesn't seem to be taking a charge. I"ll drag it back to Wally mart to day and exchange it for a new one. Does it sound like I'm missing anything? Thanks [Reply]  [No Email]

I swapped everything out and wasn"t sure about the wire from key ignition switch going to right side of solenoid cause all the diagrams didn"t show it that way. Dell confirmed that it was ok to run that way. So it looks like everything is back where it was before starter crapped out. I"m hopping the reason I"m only getting a "click" is due to bad battery, but I"m afraid it may be a bad new solenoid. Heading to get battery checked now. I"ll keep you posted. Thanks for your help and patience. [Reply]  [No Email]

"Click" is most often a bad connection at one end of either battery cable, a weak battery, a bad cable, a bad starter with a good solenoid. If with a known good battery, you still have same results, after ensuring connections & cables, give starter housing a good solid 'whack' while holding the start button down. Sometimes this will temporarily gain brush to commutator contact when brushes/brush springs are shot. [Reply]  [No Email]
