Hi ,thanks for ur response, I was following the wiring on the back of the board , from relay 1A coil terminals A&B , A - 3wires (1 coming from bottom of resistense R1A1 , reading to ground 170 vdc)(2 coming from rectifier SR1A)(3 coming from 2nd top contact on 2A relay) 1A COIL TERMINAL B 2 wires (1coming from capacitor C1A1 reading to ground 169,5vdc ) ( 2 coming from top resistense R1A3 ) now reading coil terminal A to ground 170 vdc , coil terminal B 169, 5 vdc , but reading A to B gives me 0 vdc and 1A coil doesn't energize , if I press it manually it hold it in and pull relay 2A , car runs high speed but it doesn't do it automatically , and mechanically relay 1A is ok , there isn't much tension on the relay sprin
