I've had my 24v hzj77 for a year now, and have really enjoyed getting to know it. One of the things I was always impressed with was how quickly it started, even in the cold.
In the time I've owned it, I've done a lot of maintenance to get it up to what I consider a baseline. This includes new injectors, cooling system refresh, and a good cleaning of the fuel system using a purge product. Recently I adjusted the timing using the factory SST and a dial indicator, to correct excess black smoke on acceleration. Around this time, I began having issues with excess white smoke on cold startup. I assumed it was because I had advanced the pump too far, but no matter where I set it, the smoke persisted. I had planned on new gp's anyways, so i replaced with oem units, but no change.
I'm finally looking at the glow system itself (probably where I should've started?), using the FSM as my guide.
Bus bar (through my voltmeter to ground) shows 22.4v at first glow, but once the light goes out, after glow drops to zero and the smoke show lasts for minutes, along with a lumpy idle.
The main relay passes the service manual tests. But the resistor shows NO continuity between the two terminals, when the FSM says there should be. Would this be consistent with seemingly no secondary glow?
I'm close to having this thing ready for big adventures. But "winter is coming".
Thanks and cheers all.
Edit: Factory Service Manual calls it "after glow" and indicates I should be seeing reduced voltage for about 2 mins or so after the Pre-heat, depending on water temp value...
