Why does my 92 dodge cummins charging system flutter?
When I start my 92 3/4 ton dodge cummins it doesn't charge for about five minutes and then it starts to charge when it warms up (needle flutters back and forth)? My 93 was almost the same way but worked a little faster. What is the cause of this and how can I repair it?

The cummins from that era has a intake heater assembly made to heat the air in the intake manifold. it helps with cold starts and while the engine is running while it is cold to get up to temp quicker. this is normal. you can check the amp draw with a amp meter to see if it is drawing too much. There was not a lot of electronics that were put on the 92 which should be a 12v engine. This may also have glowplugs on it as well. The 92-93 was borderline for the lowplugs depending on the build date of the engine
