Charging correctly????

Posted by tldnc on March 13, 2020 at 18:32:45 from (71.69.92.41):

Used John T’s trouble shooting guide to check charging system problem on MF 35 Perkins diesel with 12V generator. New voltage regulator was bad. Installed another new voltage regulator and amp gauge is showing charge. When you rev the engine up to 2/3 to 3/4 throttle the needle on the amp gauge goes wild swinging back and forth rapidly. Any ideas as to why this occurs and how to fix.

As always all responses are appreciated.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and ... [Read Article]
