Wait Light Says On

[Jyg101]

New Humvee owner 2001 M1035A2 Ambulance.
Quick question wondering if anyone has seen this but I have an old Presto lite PC Box
That seems to be working correct Humvee starts with no issues but wait light function is suspect.
Wait light stays on throughout the whole time truck is running.
Tested glow plug volts connected a meter to one plug and seems to be functioning correctly I get the 24 volts for roughly 6-7 seconds hear the click/thump then it drops to 0 volts but the wait light never turns off.
Confirmed this sequence many times and seems like it’s working except for the wait light staying on? Any thoughts would be appreciated Thanks

Keep the Prestolite box even with this flaw! Sounds like an internal timing circuit is bad.

Rebuild the box. Seems like an epidemic recently.

I posted about this years ago, and worked on a workaround with the help of many others.

How to bypass PCB? I am aware some HMMWV owners have done it. TOBASH

I'm not trying to speak sacrilege here, and I don't want to precipitate a war of words. :shock: How might I build a manual control box? My 24Volt Landcruiser just uses a glow wire to show glow plugs are ready, and then she just starts right up with the twist of a key. Civilian 6.2 Diesel...
