"Wouldn't the new voltage regulator brushes wear a concentric groove on the slip rings anyhow?"
No, because the brushes will bounce and never seat properly causing the alt. to not full
charge and the alt light to possibly flicker.
Typical alt rebuilding costs (1000 pcs volume):
bearings - $10
rotor (slip rings and/or windings) - $20
diode plate - $25
cleaning & re-plating hardware - $5
misc. parts - $2
damaged cores (per 1000 units) - $5
dis-assembly/assembly - $3
testing - $2
regulator - $15
Total Parts & Manufacturing Costs - $87
Markup to distributor (30%) - $113
Markup to retailer (20%) - $136
Markup to car owner (30%) - $176 (Which is low, since that's just about the shop cost.)
Yes, you can buy cheaper (junk) rebuilts from the typical retailers. Then be prepared for
multiple R/Rs to get a good alt installed.
