If you have a gear reduction that looks like this repairing is simple. Most times the contacts simply wear out.
Take the three bolts out and you'll find the plunger, remove it.
Then you'll see the contacts, notice the one going to battery wears out faster than other.
Remove the contacts by unscrewing the 14mm nut holding it in, you'll find a group of insulators as well. I've laid them out in order.
Replace the bad parts and reassemble.
If you need the contacts give me a call at 912-323-1378 or send an email to Tercelgts at comcast.net , shipping and parts a re $10 in lower 48.
SPECIAL: This month only free alternator brushes with holder for every contacr set sold.
I need specific application, make, model, year, size engine ans transmission auto or manual. Region helps also as many are different.
