[Jerry De Santis]

Stefan, Save time and money and try the following simple things first to see if the problem is either the regulator or fuse.

1, Since it is the front engine Alt. light that is the problem, switch the regulator from the rear engine to the front and take the front regulator and put it on the rear. If the flickering travels with the regulator you know it is that regulator. Don't know about the old regulators but the newer units are adjustable.

2, On the pilot side firewall, you will see two fuses. Take the fuses out and clean the saddles they sit in of all crude and replace.

Good Luck
