TO30 Wiring Suggestions

Massey Ferg55 · Sep 18, 2019

I have a TO30 that was converted to 12 volts and all the wiring from all the components was missing, so I have no idea what the correct connection sequence is what as there are many diagrams on the web. Is there anyone that can explain the proper connection flow with the components of the tractor listed below? Thank you very much and looking forward to getting this 1955 TO30 back to life.

12V Battery (550 CCA)
12V Solenoid (3 Posts)
12V Starter
12V Alternator (Single Wire)
12V Coil
Distributor
Starter Switch
Ignition Switch (4 poles with the middle pole stating Start
and the surrounding posts list IGN, BAT, ACC.)
Oil Pressure Gauge
Amp Gauge

Thank you but that picture diagram has a Regulator listed. The Alternator has its own internal regulator so I do not have one on this tractor.

There is a delco alternator diagram on fena site. For 1 wire alternator, ignore 1 and 2 pins on alternator, run wire from alternator output to ammeter, other side of ammeter to large + battery cable at starter switch. Run a wire from alternator side of ammeter to Switch power input.

I would use 10 ga wire from alternator to ammeter and ammeter to starter switch. Other wires can be 14 ga.

Ignore wiring for generator and regulator
