I trying to wire up a 440 in a street rod,, It will turn good in the start position but wont start till I quit try to start it and let the switch spring back to on position,, If I direct 12v to the resister, she fires up immediatly,, seems Im not getting 12v to the resister while the engine is turning,, I think I need to get full 12v to the coil while it is turning over... any ideas for me??? thanks in advance
