Talking about an '87 E-350 with a 460, automatic and Holley carb.
Battery has 12.7 volts. With ignition on, wires on harness [detached] going into the coil have 11.8 volts. With harness attached there are only 5 volts at the coil. Using remote starter, can't see any spark into distributor. Can't figure what's going on. Any suggestions?
