I found this web page that outlines replacing the BOSCH internal voltage
regulator with an external Ford until. This is said to cure the
low-voltage output of the BOSCH alternator.

I've noticed a few posts on the low voltage of the BOSCH alternators,
does anyone think that this could solve the problem?
