Distributor Pick-Up Coil Short & Resistance Checks
- Disconnect pick-up coil leads from HEI (EST) module terminals "N" and "P" (usually Green and White). Set ohmmeter to middle range and connect one lead to either pick-up coil lead and the other lead to distributor housing. Flex pick-up coil leads by hand to check for intermittent shorts. Reading should be infinite at all times. If not, replace pick-up coil.
- Connect ohmmeter between both pick-up coil leads. Check for intermittent opens by flexing wires and connectors. Resistance should read a constant value between 500 and 1500 ohms. If not, replace pick-up coil.
