Alternator issue?

I have not re-done the ground or other wiring connections yet or done my research. Ran out of time before I needed to leave the shop for the evening.


Anyone seen this happen and want to chime in?

I do not believe I have a battery issue. It fires up really nice and quick without any oddities.

Your control box is cycling the glow plugs, should stop in a minute or two.

I have the same issue. So this is normal?

It does look normal. When moving mine yesterday I had it running a bit longer and that behavior of the plugs cycling stopped. It was about 45 degrees out when I did that and I had it run for about 5 minutes.

Very normal for the older control boxes. Cylce time is based on cross over water pipe temperature. The newer Smart Start units (that have a test plug on them) do not do this. The relay inside the control box that cycles the glow can stick and wreak havoc on the glow plugs. Therefore it is important to keep the batteries fresh (do not brown out the contactor) as to not over amp the contactor.

In the sticky above, there is some good advice on the control boxes and please stay away from the LAU control boxes. They are easily identified with a separate glow plug harness and extra hole drilled into the top of the driverside cowl. THESE ARE PROBLEMATIC!
