Red light in MKII Carrier

[rob love]

Don't overdo the tension on the belt. Fords ran fairly loose.

One thing you can do to improve it is to replace the cut out switch on top of the generator with one of the solid state units from Mac's. They had one that also acted as a regulator. Only proviso is if you boost the vehicle with 12 volts, you automatically fry it.
Edited to add: I don't see them on Mac's site anymore, but here is a site with them: http://www.funprojects.com/products/10505v.aspx

170 in the winter is fine.

Thanks again Rob . All Items not in stock . I think it’s a fantom site because the copyright has not been renewed since 2018.

Hallo . Changed the cut-off for a brand new one from Mac’s . No joy . Red light and 0 reading on ampmeter on dash whatever the rpm . Straps are ok and turn . Any ideas anyone ? Thanks .

Can you tell if the generator is putting out anything? If not it would explain the red light and you'd be running off the battery alone.

Bruce , i put the probes of the voltmeter on the battery terminals with the engine running and i get 6 volts . I assume that the geny is not putting out any juice . Am i right ? Should i look for a fuse somewhere or does the generator have to come off ?

It could be as simple as the brushes are worn or dirty. If that is the kind of work you can do, then you will have to pull it off. If not, then you will have to pull it off and send it to an automotive electronics place. Best to find one that has been around for a long time. They likely do not run into a lot of 3 brush generators these days.

Agreed, generators and starters either work or are made to work with a little cleaning and work on the brushes. If it is a catastrophic failure in the windings then you need professional help (or at least I do). Usually a quick look inside will tell you if there's a short, burning or something stuck.

A steady 6V reading (assuming what you are checking connects back to the battery) strongly suggests to me it's the generator not putting anything out.

What's that old trick about reversing the terminals on a generator to make it 'motor' as a way of checking it?

Pulling a carrier generator would be easy enough it it weren't for that friggin fan. You pretty much have to remove it or risk driving one on the blades into the radiator cooling fins. If you do remove the fan first (recommended) then you scrape every bit of skin off your knuckles working the 7/16' wrench between the fan extension and the aforementioned rad cooling fins.
