Red light in MKII Carrier

This should mean the generator is putting out a charge. I believe in the manual there is a section in adjusting the 3rd brush to change the output of the generator.

Perhaps this is all it needed.

I was going to suggest that Jordan, and didn't catch that the light did dim somewhat. Good call.


That can be done on the vehicle, but if results are not there, then off to the rebuilders to get the brushes checked and cleaned.



I had an old tamper generator that I used to run a 125v crafstman impact gun off of. I used it to disassemble the 30 M151A2s I bought out in a field back in 87. Everytime I started it I would have to stick my screwdriver onto the segments to get it clean enough to excite the windings. In hindsight I should have took the time to open it and clean things up, but it really only took a few seconds my way.

Many thanks Jordan and Rob . I will look up the manual and try to adjust the 3 brush and report back . Cheers . Bob

Robert, you can do that motoring test with the unit in place as long as you take the belt off. (take the load off)
How the light works: When you turn the key on, the light comes on. (battery voltage) When you start up, voltage coming from the generator pushes in the opposite direction. This stops any power flow and the light goes out. (or nearly goes out)
The round tin on the top of the generator is the cut out. (I think) This opens circuit when the geny output drops to battery voltage and stops the geny from trying to motor when the key is off. The voltage output is adjusted by moving the 3rd (adjustable) brush.
If you drop the belt and "motor" the geny, and it runs, then it is in reasonable condition, so you shouldn't have to pull it out.
Make sure you have good earths on the components.
Thats about all I can come up with without doing some study.
Read up on it.

Thank you very very much Lynn , most helpful information . This will save me a lot of trouble. Nice receiving advice from New Zealand . I had a good time working with the crew of one of your frigates ( Te Kaha ) two years ago in Victoria BC . Decent men and women , dedicated warriors and protectors of your country .
