Electrical mysteries

After buying the car, I get the car on the road and the generator light is staying on. When I look at the dynamo the brushes have no spring and are wedged into the holder. Bingo methinks
So I got meself one of these...http://www.autoelectricsupplies.co.uk/p ... tegory/165 and fit it...still the same
Next stop a new regulator https://www.vwheritage.com/shop/1139038 ... amp-bosch/
Fit new regulator and by the way I'm using a brand new Bosch S4 001 battery
Partial success, now the light is going out but only after around 2000 revs plus. Prior to that it still glows faintly....I haven't done a voltage check yet, but does this point to fan belt tension ? It's tight but not like a drum, I can still affect it by pulling on it
Ahhh, but to throw another spanner into the works, which of course may have no relevance, added to this mystery is the fact that also on the dial that houses the generator light is the handbrake warning light....initially this was flickering and going off when you dropped the handbrake but then coming back on.....So I immediately thought dodgy switch..
Take out the carpet and rubber boot, tried to adjust the switch but no joy.....took the switch out and it was busted so disconnected it altogether. Light goes off....thinks...problem solved, just fit new switch
Go for a drive, light flickers on and off !! No connection anywhere at the handbrake end as the wire to the switch which I removed is isolated.....so somehow the light in the gauge is getting an earth...or maybe not?
Oh, and another thing, whilst driving I think, I'll try the horn....very poor lightweight sound which does smack of poor earth as all the wires are connected, however it could be a poor contact in the steering wheel, or poor fusebox connection....
Two things done on the car that may have relevance...when I first got it, no indicators or hazards. Cleaned related fuses in fuse box with emery cloth, problem solved
New brake master cylinder fitted..
I must say I am leaning towards fuse box and that is my next port of call.
Oh I have also been up behind the dash to fit a new dash top and the big earthing point/ bolt near the offside bonnet strut looks a little corroded but very tight....difficult to get to without removing heater paraphernalia, but is this the main earthing point for all things such as gauges, horn, lights etc?
Any opinions, experience, ideas would be gratefully received.
