Yanmar L70 Diesel Kit for MEP-016

[tmuenster]

I purchased a few of the Yanmar L70 Diesel engine refit kits for the gasoline powered version of the MEP-016 generators. The kits come with all the parts to convert the generators to run on the Yanmar L70 engine.

The engines have electric start and are set up for a 24v system. Does anyone know if it is possible to convert these to a 12v system? I would like to use them to power a small boat and I prefer to use 12v if possible.

If you can find the electric components (starter, alt, solenoids etc) in 12 volt. Remember half the starting voltage is double the starting current.

I have a MEP-016D and as I recall the entire 24V electrical system consists of the starter, which will generally have enough excess power to crank on a well charged 12V battery. There is no onboard alternator or magneto that charges the cranking battery, unlike the MEP-016B, etc.

You could convert the starter over... or just set up two ATV style batteries to give you the 24V.

Id be surprised if 12 volt would spin a 24 volt starter fast enough.

I know you said 12v, but I used one of these along with two 12v batteries and it works fine. He's also a member here.

You can be surprised if you want, I have tested it connected to my 12V F250, though only in nice weather.

I have one of the small 2kw generators with a Yanmar engine. The starter was bad when I picked it up so I replaced it with a 12 volt starter.

There is no battery charging circuit and no on board battery. There is a slave connector for starter power. I took a pair of jumper cables and put a slave connector on one end so I can start the engine with whatever power source that is available.
