Red light in MKII Carrier

[Lynn Eades]

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 .

Robert,

The generator was set up years ago to just produce a trickle charge. There is not a large demand from the generator other than topping up the battery. Probably after all these years, it's time to adjust the movable brush, maybe clean up the commutator as well.

Hey Perry , nice hearing from you . Hope you are doing well . Thanks that’s very useful information and i will do that . Cheers . Stay in touch !

New news : The generator is not producing any electricity . I pulled it and i am dropping it off at the shop on Monday for an ovehaul . Thanks everyone for your help . Will report later with results .

My friend Yves and i pulled the generator from the engine without removing the blades of the fan .We disconnected the fan extension .

Hi all . The generator came back from the shop . There was a cut or exposed wire inside making contact occasionnaly . Installed it today with a brand new mechanical cutoff from Mac’s . The cutoff failed it’s job immediately as the points were sticking and the generator was draining the battery . Thank you Mac’s . I had headed Rob Love’s advice and ordered a diode somewhere else . Installed it ( pictured ) and it works flawlessly . Bought it on Epay for $30 US or so and it is said to work on 6/12/24 volts . The important thing is it works on my 6 V system . No drainage of the battery . A nice slow charge to the battery and a nice ample supply of current to the accessories . Life is good when a generator does it’s job ! The red wire is for the red light on the dash up front and the black goes to the battery . The light comes off immediately when the engine is started and the generator is pushing current . No faint red light , no flicker . The diode does it’s job . Life is good when a diode does it’s job . Throw out those mechanical cutoffs my friends and your lives will be much easier . Thank’s Rob Love for the advice !
