battery iso relay ?
 

anyone know where i can get a 200 amp battery isolator relay for cheap and not having to order online and in the winnipeg area thx. i was going to call a couple farm places but if people know exact stores that would save me time

What is your alternator's maximum output? Princess Auto had the diode type isolators on sale recently. There were two sizes though I don't think either would handle 200 amps. I think they were 90 and 120 amps. Check it out, you might be lucky.

like 120 i thing. i want one like the pac-200 just cheaper
