Just checking to make sure,what should the voltage at the glow plugs be on a 12V system,once it goes through the dash coil indicator would it drop any?
The better check is to disconnect the wiring at each Glow plug and measure the GP resistance to ground. It should be just under 1 ohm.Just checking to make sure,what should the voltage at the glow plugs be on a 12V system,once it goes through the dash coil indicator would it drop any?
Take the wires off and measure the resistance of each ....with a good VOM.Thanks for the replies,the glow plugs are showing resistance,I was concerned about 6.3 volts at them,there not working in the winter.
