The OEM Distributor with the chome box was working fine...no voltage drop...no flickering..nothing. The bulkhead connector is fine all contacts are bare metal .
But when I installed the MSD RTR Distributor...the problem started ... but now...everything is fine!
I have also renewed all wires in the engine department... incl. 4 Ground Staps ! from the enige to the firewall...from the neg. terminal of the battery to the enige block and to the radiator support... and to the relais
Greetings Juergen
