Re: Identify late fan wiring harness

You may well be right, but the presence of the 43 relay (coolant shortage unit) on it's own relay mount tells me that it is an early part. On 1986-on vehicles, the 43 control unit is mounted on slot 3 of the CE1 fusebox. And on the diesels, there is a ballast resistor behind the left hand headlamp f...

Re: Identify late fan wiring harness

Could it be a pre-85 diesel loom.

43 is obviously the coolant shortage,
And the 24 is a generic high current 'general' relay.

Re: Temperature Guage going to full

Typical values should fall between 50 ohms (hot) and 510 ohms (cold).

Much either side of that indicates a faulty sender, connector or wiring.

Re: T3 fuel gauge

It could be the ring connector on the end of the brown earth wire from the sender getting corroded or dirty. This would increase the wire resistance giving a lower than normal gauge reading. Unscrew the brown wire from the van floor. Cut off the old ring connector, and Crimp on a new clean one. Chec...

Re: Cross Engine Pipe or plenum for DH / GW

Suddenly it makes sense - I was looking at the plenum chamber on Brickwerks, https://brickwerks.co.uk/product/plenum-chamber-t3-watercooled-fuel-injection/ Where it says - Techinically this is the early version, but the only difference is it’s missing the bracket that the Idle Stabiliser Valve attac...

Cross Engine Pipe or plenum for DH / GW

Hi all, I am most of the way through building up my DJ engine with early cooling system. I am a little puzzled, as I have a cross engine pipe for the early cooling system, but it does not line up with anything. https://i.postimg.cc/qvgbw0mH/Coolant-pipe-again.jpg So I am not sure if I need a differe...

I would say it is the high-beam filament of the bulb.

Re: Faulty Fuel Gauge - Anyone Else Experiencing This?

Have you tried the earth / ground wire from the gauge sender? The ground wire is secured under the van with a self-tapping screw. The screw and / or the wire can suffer badly from corrosion due to their location. You may need to cut off the original ground eyelet and crimp on a new clean one. Ensure...

Re: Speedometer, fuel gauge, temp gauge not working

The temperature gauge will not register until the coolant has warmed up a fair bit.
I suspect at least 50°C or closer to 70°C.
So from cold (currently 20 to 26°C) it will not move for at least five minutes of running.

Re: Connector for coolant sensor missing - please help

Just for confirmation - it is listed as type 2. This is the VW notation for all transporters up to 1992. T1 - Split Screen T2 - Bay Window And T3 - Wedge or Brick. (T25 is an unofficial UK only name based on the majority of part number pre-fixes). Just for info. Type 1 is the Beetle Type 3 is the Ka...

Re: Sudden electrical death of washers, wipers, and heater fan.

Maybe the chaps in Hannover had consumed too many biers when they printed the relay casings.

I inherited a lot of O.C.D from my wife. I spent un-necessary time removing relay casings and refitting them the right way up for the fusebox.

I would not worry about orientation. As long as it works.

Re: Sudden electrical death of washers, wipers, and heater fan.

Yes - the 18 relay wants to go in the space below it's current location.

It is in socket 2.
It should be in socket 8.

Sockets are

[1] [2] [3] [ 4 ] [ 5 ] [ 6 ]

[7] [8] [--] [10] [11] [12]

Re: Sudden electrical death of washers, wipers, and heater fan.

Have you checked the X relay. Relief relay in location No 8 It is a very heavy duty relay numbered 24, 18, or 100. Other than that is the ignition switch. X pin position. It feeds 12 volts to relay No8 pin 4 (relay terminal 86) If you don't have 12v on pin 4 with the ignition on (not cranking), then...
