found out when i disconnected the main wires to the boiler ,that i had a electric shock. check with a volt meter and found that the earth lead was giving me 60volts.disconnected earth wires on the board one by one and found that the pump earth wire was at fault. The water pump is working fine,but how did the capacitor send power the the earth line,. i had a slight water leak before and wondering if any got into the pump circuit.,should i buy another pump.
