A reg van bullet fuses

help with radiator fan electrics please!

haynes says fuse no.1 30A. But is this for the later one only? Our G reg velle with the blade fuses is exactly as haynes says. 1 thick red wire and one thinner red wire in the number one position with a green 30A balde fuse.

The A reg is entirely different. It has 12 fuses. Of the bullet variety. I number fuse 1 by the cab door, fuse 12 narest the steering wheel. I have 2 colours of fues - red and white. It also has one grey relay, marked 24. On big red wire goes into it.

Number 7,9,10 and 11 have a red fuse. There is a thick red wire heading off towards the steering wheel. Think this goes to number 9. number 9 then links to number 8 in thick red wire. But it also looks like a thick red wire goes into 8 as well?

What fuse should the radiator fan be on? VWcamperfan tested the radiator motor - got nowt. He and John followed the wires back form the fan through the bulkhead to the fuse box. Mark tested various connections with his voltmeter, and found a very poor connection which he remade. The fan then worked. Got both speeds when tested across the contacts as per haynes. Wicked, we thought...sorted!

Trouble was...we gave the fan a feed.....but had taken it away from the ignition somehow. Nowt - not a light, nothing when turned the key. But had 12v at alternator. John went back to fuse box, moved a red wire, and the van has started and run fine ever since. Looks like we put something wrong somewhere!

But now no fan again. (well it certainly didn't come on in traffic the other day and she got extremely hot!)

So, could some kind soul tell me where the fan should be please? And where the feed from the ignition should be as well, in case, in owners past, things are not as they should be!

Looking in the fuse box, the big thick wires are all red, except for one that is red with a fine yellow line I think?

Thanks in advance

emma,
the fusebox has two buzbars (The power in side of the fuse arrays) did you remove the power from one side?

the fuse for the fan maybe in the seperate fuse panels above or to the side of the main fusebox

Relay5 is the Electric Fan can you trace back from this.
Im not near a early fusebox right now, so this is from memory, and im getting old apparently.........

Steve - thanks for the reply. I will have another look tomorrow, and maybe put a piccy up.

this is all new to me.... but want to understand rather than just hand it over to someone (might still need to hand it over, but at least may know what sort of intelligent questions to ask!)

thanks again,
Emma

Emma,

All I have to go by is the Haynes, (my van has the blade fuse setup).

There are a couple of discrepancies in my Haynes, in that the wiring diagrams for the radiator fan, (There are three page 12.38 has one and page 12.41 has two) show the fuse as S1 30A

BUT..... the list of........ fuse (typical) - models up to 1985 (on page 12.1) shows fuse 7 Radiator fan, but at only 8A.

I suspect that fuse 7 is the one that powers your radiator fan and that it should be at least 16A. (Do they do a bigger bullet type fuse does anyone know?)

Try working from fuse 7.

I dont have a manuel handy, but I remember posting on here that there is a seperate fuse in the self park circuit. Cant remember if it was a late van though.

try a search.

Bit early for you Tony perhaps ?

My excuse is age and more age.

PS here is the earlier thread you referred to...https://club8090.co.uk/forum/viewtopic.p ... ht=#266619

Thanks to all who assisted...it was indeed fuse number 7....and wasn't working coz although the red and white wires came out of it, no power was going into it

There is now power, courtesy of a rather large red linking wire, which looks like it ws in the wrong place. more

Now we have fan working when we test connections as per haynes - at both speeds. And the van still starts - an added bonus.

Bring on the next job!!

Thanks again
