Barry, you're talking about a 1/2" thick cable there! Its so stiff at that size that you do not expect much to go wrong! (Welding more than soldering,heheh).
For the twin fans I have (of 75 TD origin) I use one 50A relay, exactly the same as the main power relay in the 75 fusebox( the one with the big wide prongs) mounted right behind the headlight, inline with the other relays there and fed by a 4,5mm* wire from the battery.

Well, I am about to upgrade the chintzy speaker wires. I think while I'm at it, I'll take care of the window motor wires. They look like 1.5sqmm. Pretty tiny CSA.
You've got to seek out that extra HP where ever you can. Even if it's in your window motors.
I cleaned up all my earth and positive wiring connections all over the car. I then replaced the battery wire from the alternator to the battery cable connection on the firewall (with a thicker wire) this made a huge difference to my lights , windows etc and the glowing alt light.

The alternator I reckon is your first step. Alternatively,fit the winder mechanism from the Opel superboss.to uoyr car.Supply power through relays and your windows will fly up and down.The by product of all this is also to be seen at night.No more shitty headlights..

Barry, please explain. Is the Opel mechanism a fairly easy install? Do you perhaps have pics and is the wiring more or less the same? I have a snapped cable at the moment and fitting a new cable is a PITA and all I'll end up with is slow windows anyway. I'd love to have windows that don't have me sitting in the car for minutes after parking waiting for the damn things to shut.
