Funvee dead 😕

[williamh]

I think my control box died. Ran it on Friday and jumped my new Mep. Went to mone it tonight and dead , no lights - nothing. Jumped it with the Mep and still nothing. Got 28v and a good ground but not even the lights work. Looked around for a cb under the dash but it’s a little cold and dark. Any quick fix advice ?

Read my signature line.

Rebuild your box or contact me for other options.

Did you check the usual suspects like the pass through ground stud on the shunt?

A little follow up. So far pulled all wires in the battery box and cleaned. I don’t know what the MC has with silicon but what a mess. Nothing looked bad but cleaned it all up. Found the front battery is really weak , put it on a rejuvenating charger and gonna wait to see if it comes around.

 

[williamh]

It’s all just bad news , cleaned all the electrical and replace the batts. Lights are happy but as soon as I turned on the ing. switch , I can gear the fart box relay click than the wait light comes on for 1/2 second and everything goes dead. So hopefully tomorrow I can pull the box and look inside to see what’s up.

Let me know what you see in there. Here one to study. Recent customer with no start condition. Something to do with the smoke was released.

No it wasn't in the LA fires, Camo

Toasted? LOL that thing is on fire still.

 

[williamh]

Oh it should be fine….. little contact cleaner and a wire brush. Should clean up fine

Easy to rebuild.

Here’s a little update. It’s good and not figured out. After cleaning up all the electrical and replacing the batts , nothing changed. After connecting everything back up the lights and everything would come on but as soon as I turned on the Ing. everything would die. So I re pulled the batts and wires then pulled the smart box. ( last time someone replaced it they put in bolts too long and stripped the nutserts. Had to cut all the bolts ) so I pulled the smart box apart and everything looked perfect. So I check all the wires and everything I could test looks good. All plugs look good and pins all check ok. Re install everything so I can start tracing a bad wire ? Now everything is working proplery . Must have started it 50 times since then , no idea why it now works.

You wiggled an intermittent connection such that it’s good for the moment.

 

[williamh]

I’m sure you’re right. I just haven’t found found it yet. Being sick for a week and now raining doesn’t help the search. I’m sure it will pop back up , I’m hoping it won’t lead to a total meltdown.

One of my trucks went dead when I was driving it. Initially I was exasperated, and then I realized I had been working on the electrics replacing the protective control box with one of my genius boxes. When I checked my connections, turned out that one plug had fallen off because I did not completely tighten it.

Recently, another member here posted that his truck went completely dead. I asked him to check the same PCB connections, and sure enough that was the culprit.

When you take everything apart and then reattach, you can restore a connection that was either loose or corroded. You may never know exactly what was loose or corroded if the above is what happened to you.

NDT is correct also. Carry a tool kit in your rig.

Had you re-seated the inside and outside plugs on the EESS box before?

 

[williamh]

No. I did check for tightness originally and there were very tight. I’m sure it will pop back up. I thought it might have been because the box was loose with the mounting bolts ? It should have been grounded threw the wire harness.
