<www.dratv.com> has wiring diagrams, the c100 is same as older
6v c70. He has many parts you can use but is a major asshole if
you question him. Watch freight charges, he once billed me $60
to ship 2 passport tires ($40). His wife fixed it but he continued to
harass me after the refund. (But he has cheap parts)
Many parts I get overseas through E-bay, type c100 into search.
contact the seller with a list of all needed parts and ask for a total
cost with shipping, it will save you $. Shipping takes 4-6 wks.
