Thanks to all of you who helped walk me through it.
One thing I like to do with mowers is remove the mower deck, clean it well, and paint it with bed liner. It cleans off easier, and absorbs impact from rocks so the paint doesn't chip on the outside of the deck. It also prevents rust from acidic...
The part is a Briggs and Stratton 393456 alternator diode assembly. It has 2 wires(1 red, 1 black) on one end and a plug with 2 pins on the other. I looked up the schematics for its installation and found the diode is in the red wire, so the black wire I did not connect, just tucked it into its...
Victory!!!!
I installed a resistor inline on the blue wire between the ignition solenoid and the brake actuator.
I also checked for corrosion on any pins at the connectors basically everywhere on the mower.
Hooked the battery back up, and the engine fired right up and shut back off with the...
I looked on Mouser.com, and got really confused. So I went to Oreillys auto parts website and found a "Littlefuse 1 amp mini diode" that would plug into a fuse holder I could install inline. Would that work, or is that high enough ampage?
The brake controller had malfunctioned, in that the brake wasn't releasing when the steering arms were moved from the "park" position. (sometimes they would, sometimes not)
I purchased a new (not reman) brake controller online specifically using the info from the mower. After installing the new...
You are understanding the problem correctly. Once the ignition switch is turned to "start", the starter remains energized even when ignition is moved to the "off" position, until I disconnect the ground.
What sort of diode should I install, and where do I get one? I have rewired entire vehicles...
Clarifying... With the blue wire disconnected from the "brake controller", the solenoid buzzes.... I had typed "switch" which sounds like the ignition switch...
With blue wire disconnected from the brake controller, the solenoid will buzz for a moment, then starter will engage and engine...
Haven't been able to get back to mower for a day or so. Planning to make time later today, I hope.
When ignition switch turned to run, without going to "start" position, there is no power to the starter. It only gets power when turned to start. Once in start position, power remains to starter...
Gotcha. I'll do that as soon as I can. Thank you for the clarity. I get the basics of electricity, but struggle with understanding how feedback and diodes work.
Traced blue wire from brake controller up to ignition switch. Disconnected at that point. No power to starter. But when reconnected and turned key, starter engaged. When disconnected while starter running, the starter kept going until I
Cleaned and tested continuity for ground to motor and for brake switch. All tested good. Re-tested starting the motor. Same issue. But...I thought 4 post solenoids didn't matter if they were grounded. Wouldn't work if not grounded. When I grounded it and starter kept running even with key off, I...
