I was roaming the junk yard, found a starter laying there off a V6 Minivan. I searched the web, found 6cyl normally pulls ~175 amps. I took the solenoid off, but kept the gears. Hooked it up to a 14.4V Dewalt 2.4Ah battery, it spins both ways depending on the wire to terminal setup. I got some 14AWG wire for grounding to the case, used one strand, it gets hot, tied two strands together and it heats up, 3 strands together equals ~#9AWG and its normal. Bought some #8AWG off of ebay which is the same size as the wire that came with the starter.
I was thinking I could pulse the voltage, wire up a computer fan to cool the motor, maybe figure out how to drill holes on the case to help the cooling.
The switch, I can easily buy 50A DC toggle switches around here, but I am thinking I need more like 100A DC switches so they dont "weld" closed, for safety reasons. Maybe put in some fuses, find an old circuit breaker rated for 100A, but those are meant for AC.
I will see where this leads, I might downsize the starter to a 4cyl (130-150A), or even 3cyl (110-120A) perhaps even a motor cycle starter (85A), then if the amp draw and heat is a no-go, its onward to the 24-36V cordless mower motor.
Oh and yeah, I am going to buy one of those amp-voltmeter guages off of ebay, looks like most of them are coming outta China. I tried a el-cheapo Motormaster MultiMeter, but 10A range is no good. Plus it literally vapourized the tip of the probe, hopefully the clerk wont notice it, I sanded it down a little bit.
