Smart Start Box, Glow Plugs, Sensor question

[RJTM998]

Alright, guys had a couple of questions and needing some advice. MY M998 6.2 (Prestolite Box, Wellman glow plugs) was smoking on start up and was showing no glow plug activity on the volt gauge. I had the glow plugs switched out and all seemed normal and was operating as it should for a few days. Volt gauge showed plugs coming on during "wait" light startup and then cyclce a few times after startup and go to green showing charging system.

Then I was driving it today and I noticed my volt gauge jumping around and clicking from the start box. It was doing this while sitting at a stop light, not on startup. I got stopped and the clicking kept going. I unplugged the sensor and it stopped clicking at the start box. I am not sure I didn't kill my glow plugs again.

Start box? Sensor? Glow plugs? One suggestion I heard was try a new sensor first and see if that fixes it. (Because I have the Prestolite it is not a common easy to find the sensor.) My issue if that was not it I would be switching to the more common Nartron or KDS box which requires a different sensor.

I am tempted to just start over with a new Smart Start box, sensor and new glow plugs.

Can installing a new start box and sensor and not plugs hurt the new start box? Trying to not change plugs again if they are actually good.

I have read you need a certain alternator for certain start boxes?

Nartron? KDS? Which is the preferred box?

Also considering going with the new Camosystems manual glow plug box. Thoughts?

If you were in my position what would you do?

Thoughts? Thanks guys!!

BUILD YOUR OWN BOX!

CAMO makes a solid product BUT it ain't hard to build. I also sell them, but why not save the $ and DIY?

The design was created with CAMO's help all that time ago.

Look for posts # 1 and #51 for schematics with parts list and instructions.

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...

If you guys saw my first post I am having start issues. I am strongly considering going to one of the manual start box setups from Camotechsystems. Any you guys have any experience with this setup? Thoughts?

To me, it seems like a simple solution for a known issue with the HMMWV system. The Smart Box is probably the # 1 thing that people fight on these trucks constantly. I have spoken with Cam directly and he seems very knowledgeable and a nice guy.
