Thank you guys for your help. Neutral safety switch it looks like. ***SOLVED***

That wasn't it. Gauges all activate when I turn it to "run"... but turns out my neutral safety switch is going out. When I tried to start it shifting back from neutral to park, I really jammed it home - and it started.

Yes sir - but separate from start paddle. It just turns power on and off. Original start paddle controller - but that could be the issue, I suppose. Just strange that I has worked perfectly up until now. I am also investigating the neutral safety switch.

Yes sir. Still can hear it engage and everything...

That was my initial thought as well. I have shifted through both shifters - to N and back, but nothing changed.

I have been driving it pretty regularly with zero issues or symptoms. Last day to drive was Saturday and I drove it off and on all day. Today (Monday) went to start it and got nothing. "Wait" light lights up for 8 seconds on cold start, voltage needle "bounces", but get zipp from starter - no...

My understanding is it free-wheels until set temp is reached, then engages. I would imagine you ford with engine at cooler temp and water will keep engine cool after entering. Is that incorrect?

viscous fan clutch should free wheel when it hits the water. The Black Dog clutch is fixed, so I may be screwed on fording. AI told me it's possible, but I don't like the idea of that at ALL. Anyone know of an upgrade to viscous fan clutch for an A2 engine?

Well, that sucks. No plans to ford, but I hate that it isn't an option in a pinch... well, I guess it IS an option - just a one-timer, lol.

Sorry, forgot to mention former owner installed this kit (but was still having overheating issued because he only had electric puller fan).

So, I replaced temp gauge, flushed radiator thoroughly and installed new 195 degree thermostat in addition to replacing eletric fan with new upgraded Black Dog mechanical fan. Now temperature gauge sits just under 180 degrees unless I push engine hard in 90's+ outside temps - where it gets...

Can confirm - amazing performance. Black Dog rep said while he hadn't actually tried water fording with this kit, he believed it "wouldn't be a problem"... Any idea?

Replaced electric fan with Black Dog hydraulic fan clutch delete kit upgrade. HUGE difference! I have electric "pusher" fan on top as well, but won't use it until I get my 120 Amp downcoverter 12V system installed - as I think former owner's 12V electric fan is what killed the regulator. Just...

This fixed my blinker issue. Still working on break lights. I have narrowed it down to either the brake switch itself or the linkage. Does anyone know if the same year (2001) Hummer break switch is compatible? It is like $7 at AutoZone...

Update. Went through diagnostic flowchart and determined regulor was bad. Swapped it with used one from Dubai and this solved my issue!

Great, thank you!

Can you tell by looking at this picture? Belt is back on so I can't try that now...

Yes, I printed it out and have read through it. However, I did not see anything about the clutch pulley - or perhaps that is broadly covered by the "alternator is defective"... I will take it with me when I go to my son-in-law's to test everything.

Thank you - will do. I hope to get the assistance of my electrician son-in-law. My one concern was the clutch pulley. I have heard those can cause my issue - but I am unsure how to diagnose that. As I said in the opening, the generator pulley turns easily and smoothly by hand with the belt...

Yes, will do - thank you!
