    No Voltage/power on 28v gen set

    Will try for Monday with pictures of the set and control panel. I assume inside also.

    No Voltage/power on 28v gen set

    Used the new unit for the first time to charge and boost new Mack powered tractor. Runs great, showing 50-75% load @ 28 volts on charging, but kicks out the CB when you crank the engine too long. Likes gas too, 1 gallon in about an hour. Batteries ar mostly NG so high rate of charge is not a...

    No Voltage/power on 28v gen set

    Got the new regulator from Saturn (normal great service) and installed. Unit now runs great and makes correct voltage (22-36 vdc on gage). Also installed new air hose between filter and carb, new spark arrester (a little less noise) and new air filter element. Where would I get the...

    No Voltage/power on 28v gen set

    Checked the ohm readings on the fields per the TM. Both came up as within tolerance, so I guess that the regulator is the problem. There are no brushes on this type of gen set, so that can't be the problem. Next call is to Saturn. Also won it's brother (120/230 volt) on Ebay last night so...

    No Voltage/power on 28v gen set

    Thanks all for the input. The little 24 volt unit's regulator is a round can like thing (looks like a little oil filter) mounted on top of a squarish base (maybe 2"x3") with terminals on one side. Haven't taken apart yet, but it looks sealed. Good question, if idling is NG why the lever on...

    No Voltage/power on 28v gen set

    Thanks for the links. Any idea on the type and kind of transistor needed, and how hard is it to change? Radio Shack as a supplier? No mention that I can find in the manual about the idling problem. Want to rig this up so we can start 24 volt construction equipment in the winter if the...

    No Voltage/power on 28v gen set

    Also, need manual for the 3 hp 2 cylinder engine on this gen set. It does not have the newer style electronic ignition like the newer units. Don't see this manual in the manul listing below.

    No Voltage/power on 28v gen set

    Yes, we picked it up from Adirondack, $200 for 6 gallons of paint and the gen set, not too bad a deal. Son is the wheeler/dealer!! I guess the problem is the voltage regulator, from what I can find out in the manual. Need to check the field and stator resistance next before I try to find the...

    No Voltage/power on 28v gen set

    At the Weare show, we picked up a 28 volt MEP-025A gen set for cheap money. Needs a new air cleaner element, a hose between the air box and the carb and the plastic tank has a pin hole in the side (fixed with screw and rubber washer) but other than these small items it is almost new. Runs real...
