Got a strange one going on here. Started the car today, took it down the block to a friend's house. Parked it and tried to restart it, no power at all. Checked battery and it was getting power but no switches, fan, radio, interior light's, etc. Now it did this a few weeks ago noticed my negative terminal was loose and tightened it. Figured that was the case. Not sure if something is causing the car to lose total power. Grounds looked good and fuses looked fine. We looked and looked and then all of a sudden I'm like just try it again, voila. No clue what is going on. I have seen my car pop up a p0620 which is a generator malfunction but not sure what that would mean because it's been throwing that code for 3 years off and on. Any ideas or thoughts?
All power from the battery to the car other then the engine bay goes through those two fusible links coming off the junction block below the C500 if it is a bad connection from the battery to the junction block every thing goes dead in the car if it is the fusible link unless both blow you only lose some things. A quick check is to see if the head lights work as they are on a separate fusible link then most of the rest of the car so if no start but have head lights I would suspect one of the links is gone or on its way out.

just went thru this , by the battery wire block their are fusable links 3 or 4 any one will stop the juice from flowin,, pop open your ohms meter and hunt it down,, that is where you will find the problem,,,
I forgot to check the headlights this last time. But the previous week it did this we had no headlights at all. My battery is moved from the engine bay to the front of the car. I will have to look at the C500 connections and see if any of the links have gone bad or just replace them all since they have probably never been replaced in the past.
Phil, this was at the 20th, where it would do this if I recall. I can't even remember what it was doing then. I know I have good parts as I have a Optima red top and a 0 gauge power wire, so no issues with getting power.
FIEROFLYER, do you have a good picture or diagram of the fusible links in back I need to check on to see what's going on?
The fan and Intercooler pump on my car have constant power directly wired to the battery on a switch. I tried to turn on both of them, nothing at all. We literally jacked the car up and put it back on the ground checking fuses, etc and it all of a sudden got power again. That's the even weirder part......
Could it be a battery going bad for some reason?

I would say check and possibly add another ground from the engine block to the cars chassis. The deck lid hinges are a good spot on the chassis for the ground. Dan

Don't think it's a faulty battery? We have 2 grounds now. One up front by the old headlight area since I have flushmounts and then another one down below.
If front mount battery check wire comjng off starter to the junction box under the C-500.... Small gauge wire that was added to power the junction and wiring going to it.
The strange part though is the fan and ic pump are directly wired to the battery and it didn't have power either which makes me really think it's a ground issue more than a fusible link.

Going to try and add another ground like FIEROFLYER mentioned and double check again the existing ones just in case one more time. I can only think of a ground causing such a thing, but with my fan and intercooler pump directly wired to the battery, I still have no idea why there was no power at the switch or anything.... so weird.
