Broke down

Thanks I wasn’t sure about both wires I know the 1 is fused looks ok . I did have a little bit high voltage reading. Figured I have a battery shorting out maybe. New one at home

 

It’s running normal since last night. Didn’t want to take chance goona have to clean grounds and run with it. Can’t get it to replicate

 

Thanks I see a possible in line fuse at starter. All I did was shake some wires and nothing for a minute or so. While trying to open fuse box Cops showed up asked if I needed tow Truck and suddenly no reason buzzer came on all normal ( had key on) started right up.Im trying to get bulb changed in dash for yellow check engine to check stored codes. Lol I never changed one and trying not to break anything

 

. Do you know what this is for? Sits in bottom of fuse panel EDM electronic data monitor

 

Very good info will read all now. Wipers work fine. Don’t know about while Truck was dead though. I see it controls fan switch already have had problems with it . Great info I’ll read it and get educated. I have 1 bad wire to edm hasn’t broken yet just green has been damaged . Will fix anyway need to know if this thing can shut me down or just communicates info etc . Great info been trying to find out what it does . Thanks. I gave up trying to fix yellow check engine bulb looks like sealed cluster .tiny bulbs look to be soldered in. Don’t think I’m throwing codes anyway . Got to be ground.Trying to avoid Tow or shutdown on way home to Michigan Everything’s closed down here in La.

 

Trying to replicate problem no luck. Going to clean all grounds and recheck any fuses for battery ecm starter. Fan working as should per file you sent. A/C Freon has disappeared ( dyed green) must be a mess of a leak somewhere under bunk or in Cab. Unrelated though.Thanks for info on EDM I can at least rule it out. I’m thinking bad ground affected abs light first as low voltage/ amps ? Then shutdown? As abs then red shutdown cams on then off before abs went on and it just died out and lost power to ecm and dash warning lights / buzzer. Thanks again
