Are you checking at each injector with the harness un-plugged? Otherwise you are seeing other stuff. All the injectors are wired in parallel. So with all plugged in the ECU is seeing an ~4 ohm load. At ~12 volts that is ~ 3 amps. If you have the wrong injectors at only 8 ohms each that becomes a 6 amp load which can toast the ECU. The air cooled engine used lower resistance injectors but there was a resistor in the circuit. Dennis

I'm going through and checking what I can to see if there is anything out of spec that may tell me what happened so I don't get stranded 500 miles from home. I checked the resistance of the electrical plugs at the fuel injectors. All four were 8.1 ohms. According to a ProTraining manual i have, it should be 14-18 ohms. It's interesting that they are exactly 1/2 of what they should be. I'm not sure what this means and the manual doesn't say what to do if the resistance isn't within range. |
