The ideal main brush positon is where the voltage of adjacent comm bars is nearest to equal, where least sparking occurs. The position varies with direction of rotation and output. (one reason adapted VW dyns not ideal) The DEL does have provison for slight adjustment. I dunno who initially adjusted or how; customary to set at mid range if disturbed as most by now have been.
The original ammeter is very low resiatnce and ideal for the application. It can be calibrated in series with fancy one. Can do in comfort off the car using a battery charger and sundry bulbs.. Meters will not tolerate grossly excess current as when short circuited.
