mrtn Posted September 13, 2016 Share Posted September 13, 2016 Mk1 diesels have had regular issues with alternator grounding. Worth checking. Quote Link to comment Share on other sites More sharing options...
G B L Posted September 13, 2016 Share Posted September 13, 2016 You are doing all the right things. The fact that charging the battery cures it for two days is very interesting. Knowing the level of charge of the battery after two days before the charge would help. Do you have a hydrometer ? Quote Link to comment Share on other sites More sharing options...
PATWS6 Posted September 13, 2016 Author Share Posted September 13, 2016 That's why I added an additional ground from the alternator bracket to the frame and it still is doing it. No I don't have a hydro meter Quote Link to comment Share on other sites More sharing options...
G B L Posted September 14, 2016 Share Posted September 14, 2016 Would like to know if the state of charge of the battery is less after two days. I need to see the wiring diagram for the Gen 1 Quite a puzzle Quote Link to comment Share on other sites More sharing options...
PATWS6 Posted September 14, 2016 Author Share Posted September 14, 2016 Noticed today while driving that it will constantly lose power gauges flicker and radio goes off. If I floor the car and bring the RPMs over 3k it suddenly has all the electrical power in the world and all the flickering stops. I know it's got an internal voltage reg on the alternator all wires seem to be in tact I traced it back through the loom. Stumped thanks guys Quote Link to comment Share on other sites More sharing options...
G B L Posted September 15, 2016 Share Posted September 15, 2016 (edited) No chance the belt is sliping ? IF you open the hood just after you shut off the engine is the alternator pulley very hot ? Edited September 15, 2016 by G B L Quote Link to comment Share on other sites More sharing options...
PATWS6 Posted September 17, 2016 Author Share Posted September 17, 2016 (edited) Belt is tight it's doing all kinds of s**t now like not turning the fans off Edited September 20, 2016 by 103west43rd Profanity Quote Link to comment Share on other sites More sharing options...
G B L Posted September 17, 2016 Share Posted September 17, 2016 Does charging the Battery after two days still Help? You need a good scan tool that can check the BCM (body Control Module) Quote Link to comment Share on other sites More sharing options...
PATWS6 Posted September 17, 2016 Author Share Posted September 17, 2016 Yes it does still having the problem. Fixing to sell the csr Quote Link to comment Share on other sites More sharing options...
PATWS6 Posted September 19, 2016 Author Share Posted September 19, 2016 (edited) High cool fan was not working due to a 50amp fuse blowing. Ac was low 2 cans. I ripped the whole wiring harnass apart starting at the main fuse box under the hood. Started with the largest wires and traced out and confirmed either 12v 5v reference or ground. Found all kinds of s**t. The power junction splice between the alt coming in and battery coming out is a complete cluster f**k. Anyway the van is running great ac is mega cold and I didn't find anything to confirm a ground or power issue, so I'm sure the problem is still there we have only put 100 miles on it. I don't know where else to go with this issue. Again, i can only confirm its a power issue when the problem happens by going WOT once over 3k RPMs it has all the electrical power in the world.

G B L Posted September 19, 2016 Share Posted September 19, 2016 Hey fixing the fan and the AC could make the under hood temps much lower. The Alternator output and voltage gets much lower as the temp rises. You may have found the issue. Looking forward to the next post.

Prairie Pyro Posted September 19, 2016 Share Posted September 19, 2016 I recently had AC issues on a large truck and that the cab fan would not run and once the R134 was back to normal levels all was well again. The smart logic to save systems sometimes can be perplexing. 12 bucks for the R134 sure beat a new controller or fan assembly. Good luck Quote Link to comment Share on other sites More sharing options...
PATWS6 Posted September 22, 2016 Author Share Posted September 22, 2016 Van still acting like the battery is dead when u turn it off and take the key out all you can hear is a relay clicking super annoying and it won't go off until key is in the on position Quote Link to comment Share on other sites More sharing options...
G B L Posted September 23, 2016 Share Posted September 23, 2016 The relay cycles when you switch the ignition off? For how long. If it cycles can you trace where you hear the noise? Quote Link to comment Share on other sites More sharing options...
PATWS6 Posted October 2, 2016 Author Share Posted October 2, 2016 It was the small ground wire that is grounded at the battery the crimp on eyelet had a bad crimp/connection. Hasn't seen problem again. footnotes: these vans are G A R B A G E Quote Link to comment Share on other sites More sharing options...

PATWS6 Posted October 3, 2016 Author Share Posted October 3, 2016 It was a factory oem connector that was bad let it be known Quote Link to comment Share on other sites More sharing options...
G B L Posted October 3, 2016 Share Posted October 3, 2016 Hey Lots of cars from many different factories have had electrical connector issues. It is never a pleasant experience to be in the middle of that kind of problem. You at least have the satisfaction of knowing how much time it took and not having to wonder why you got a giant bill for what seemed like a small problem. Hope the Service from your Van continues to improve Quote Link to comment Share on other sites More sharing options...
