I can't get power passed the firewall to make anything under dash back to work. I've replaced circuit breaker, cleaned points in horn relay. Engine runs fine by hot wire, gen charges but no lights anywhere no ignition. Nothing inside works. Have cleaned all common battery connections, both ends of both batt cables, solenoid connections. I didn't have horn before cleaning points on relay but now have low tone. passenger side does nothing so disconnected it. I did run a jumper wire to it and wire got hot, hence my disconnecting it.. All I can say is HELP.
Thanks in advance,
