OK, All fusaable links are good. Bat. 12v, Alt output 12v. I have gauges no light. When key is on the gauge will discharge very slightly. I have power on both sides of the horn relay. I did bypass the regulator with a jumper from F to 3 with no change in Alt. amp output Voltage Regulator 3 has power all the time 4 power when key is on I have a condenser connected to the back of the regulator. I don't think this has anything to do with the problem ? Does the relay on the firewall next to the power break booster have anything to do with this. When I pull the Ignition switch what am I looking for? Thanks everyone for your help. Paul
