OK, so I'm wrong here. This can not possibly be a Wolfsburg wiring schedule. VW to my knowledge, nor DIN, has ever had a brown wire carry positive voltage to a load. If it were my car, I would change the wire colors or at the very least paint the first few inches of the brown red. It just can't be safe to have conflicted color coded circuits in the same vehicle.
So although I back down, I still maintain confusion as to how such a system could have come about.

It is not at all unusual to find that colors don't match up when attaching the DIN factory harness to some accessory, be it a fan motor, fridge, stereo, or other. |

Woof, I got a scare there. And I have to say, I was also confused that they had such color changing wires here. The brown, blue, etc. wasn't even reflected in the Bentley. _________________ 1984 1.9L Westy |

In the case of the fridge, Dometic is to blame.
There's a diagram on top of the fridge with the color codes on it. This is on my Rm182B (1990 Westy with automatic piezo):

Anyone with a ProMariner ProSport Dual Bank charger have it hooked up to only one battery? When I got this it was charging aux and starter battery (both lead acid) but thinking LiFePO for aux moving forward and wondering if I can use the lithium charge profile (20amp model) to keep aux battery charged, but assuming I don't want that charge profile on the starter battery, so thinking of simply disconnecting from starter (alternator does a pretty good job and might get a trickle charger for winter maintenance, but that's later)
can you run these with only one battery hooked up? _________________ '85 Westy full camper, Subaru 2.5L, 5 speed SubiGears + 5speedbus shifter kit |

Thank you all with the help on the dometic fridge. One thing I realized it might eat up my lifepo4 100Ah battery. If the dometic takes 7 amps, would it be 12v x 7 amps = 84 Ah or is it just 7 Ah? I hope it is the latter. . . _________________ 1984 1.9L Westy |

In one hour it's be 7Ah, in 12 hours (nothing to do with volts) it'd be 84Ah sucked out of the battery. As you don't really want a LiFePO4 battery to be outside of 10% to 90% charged (so 80Ah available in your case), that 84Ah is more than your battery can give without excessively shortening its life.
Don't even bother to think about running the fridge on 12V power without the engine running. Your 100Ah system will be fine for lights and radio etc for a couple of days, and that's it. _________________ Jim Crowther

Can anybody provide a comparison of relative compression and rebound damping between OME, Bilstein (black) and Bilstein HD (yellow) Syncro shocks?

Is there any reason for a daisy chain of ground cables that are strung from the engine ground to the little stud/bolt next to the distributor, then to 2 of the stud/nuts on the base of the breather tower?
Is it possible the main ground location isn't "grounded enough"?
Is there an "Official WTF was the previous owner thinking" thread? _________________ ———————

That covers about half of all the threads and posts on TheSamba. The other half being "WTF was Volkswagen thinking?" threads. _________________ '90 Little Blue Truck, 2WD auto, FAS GenV 2.0 NA (AVH) |

You might do a but better than this
The draw will be 7A x hours * duty cycle, which will depend on the temperature , by the typically 33-50%
7A seems high , though, they typically pull 2-3A once started. _________________ .ssS! |

Abs I think the fridge is the stock Dometic using the 12V heater element. Not a low energy use compressor fridge Dometic. _________________ Dave O

No duty cycle on the old Dometic. It takes 7A continuous. There's no thermostat control. _________________ Jim Crowther

A/C was struggling, suspected low refrigerant.
Found Schraeder valves were leaking, tightened both.
Recharged A/C w/ 2.5 lb R134a.
Now compressor cycles on for 30 seconds or so, then shuts off.
Eventually blows coldish air.
What could be the culprit?
Note Subie compressor was plumbed to VW system by P.O. at motor swap with conversion high and low pressure fittings installed. _________________ =BCE56=
