theboz 0 #1 Posted September 28, 2020 I have a K301s in a Deutz-Allis, it is a replacement motor but I have the original that I want to rebuild and maybe keep to put in a WH with no motor. The Deutz hasn't run for a while. Found a ton of corrosion and found a mostly disintegrated component that has no distinguishable markings left. It looks like it is wired in between the ammeter and the ignition switch. I will have to make a new wiring harness for the second motor and the deutz was going to be the template. Could it be a fuse?

bc.gold 3,399 #2 Posted September 28, 2020 If the voltage regulator had a diode leak Alternator diode draining battery This could cause the battery to run down over time. Diode failures may also allow AC current to leak into the electrical system. ... A leaky diode also can allow current to drain out of the battery through the alternator when the vehicle is not being driven. A faulty voltage regulator can also cause charging problems. 1 Share this post Link to post Share on other sites
theboz 0 #3 Posted September 28, 2020 The battery leaked and ate most of the connections, this is the only unidentifiable object. Share this post Link to post Share on other sites

Frozen battery or over charged. Mix up a solution of baking soda and water, pour this over the corroded parts, this will kill the acid saving whats left of the battery box.

I don't know if tha tis a Allis part or a Simplicity part. What was it connected to? Are there any wires coming out of the flywheel cover? Can you post a picture of them if there are wires?

Baking soda on everything was already on the to do list. Share this post Link to post Share on other sites

It is a late 80s Deutz, pretty sure it was made by simplicity at that point. The wires went from positive side of the solenoid into one end the component then the other side comes from the wiring harness, can't remove the battery tray easily, but the same color wire comes back out and into the ammeter, which then goes to the ignition switch.

gwest_ca-(File Mod) 10,495 #8 Posted September 28, 2020 Is it a model B212 or H212? The engine was made in 1986. Looks like what is left of a circuit breaker. Garry 4 Share this post Link to post Share on other sites
bc.gold 3,399 #9 Posted September 28, 2020 (edited) Some heavy equipment operators called these battery disconnects we called the, night switches, if there was a stray current discharging the battery overnight this switch was installed to break the circuit. I believe the previous owner had a battery discharging issues and installed that miniature switch to break the power circuit to the voltage regulator when the machine was being unused for extended periods. Or perhaps the voltage regulator was overcharging, had t his been the case he would have run the machine with the circuit ( switch ) in the closed position then at some point broke the circuit and run off battery current. It's a band aid. Edited September 28, 2020 by bcgold Share this post Link to post Share on other sites

Garry That definitely looks like it, the plastic is even eaten though so I couldn't find any numbers or letters. On a side note the tractor is a Duetz-Allis 912h that my grandmother bought new when she had her buisness. Edited September 29, 2020 by theboz Share this post Link to post Share on other sites
theboz 0 #12 Posted September 29, 2020 I found this diagram here on a different post, I'll have to look again when it is light out but I'm pretty sure that the circuit breaker is in the same place as the fuse here. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,495 #13 Posted September 29, 2020 Look at item 33 below the battery. https://www.partstree.com/models/912-h-1690516-allis-chalmers-garden-tractor-12hp/electrical-group-7112-7114-7117-7119-early-models-6/ May be the wrong part because there are 3 other 912H models listed. 1690516 (above) 1690521 1691131 1691125 Let me know if you find one of these model numbers.

theboz 0 #14 Posted September 30, 2020 Well good news, after cleaning a few connections and putting in a new circuit breaker, it ran great. Thanks for the help guys. Share this post Link to post Share on other sites
