RGS Electrical Shortcomings?

Lads,

I'm careful about searching the extensive archives before asking questions, and I have searched for whether there are commonly known electrical shortcomings in the RGS system that should be fixed. There do not really seem to be any, with indicators the electrical system is pretty well designed.

For example, on my '95 Moto Guzzi Sport 1100, there are a few known electrical things to fix - ground the gauges individually, run ground strap from main R/R ground on front fairing frame to chassis, etc., refresh relays, all things I did. I'm going through my "new" RGS with a few updates, and am checking to see if there's anything electrical to attend to. I have Dyna coils coming, cleaning all electrical connectors, and am relaying the front headlight. Any other things sparky to do?
Thanks-

Kristian

Indeed it is.
Replace the original reg/rect because it's 30+ years old and will let you down by ceasing to regulate and fry your battery.
Fit a replacement that can cope with the full alternator output (a heady 210w!) and remove the switched alternator coil output through the headlight switch. So you simply connect the alternator direct to the reg/rect, replacing the discoloured bullet connectors that are going high resistance as you do so.
You'll then not need to worry about the overheating/melting pin & socket in the 9 way connector to the LH switch block under the tank.  However, do check the remaining 8 pins for corrosion. Relays for the headlight will reduce the consequential volt drop there.
The frame earth (green wire) on the electrics plate mounting at the rear o/s of the tool tray is bent over the rear mudguard bracket. This is a known potential (ouch) failure point too.
 
To add to what Rob said:

Starter relays have been known to stick on.  Some say replace with new*, some say pull the old one apart and clean the contacts.

* e.g. Bosch 0 332 002 161 which has, to quote Piet, "an internal resistor/diode thingy to prevent electrical peaks entering the system during or immediately after the cranking process".
