Hi there, I m doing work for a friends MF. I replaced the battery, shift lever start button, voltage regulator, ammeter and coil. Still will not turn over. If loses voltage when the start button is pressed. Everything g is hooked up the way it was. I have the serial number for reference. It s also a gas engine. And from what I have researched and been told and 6 volt system. Also no key required and no solenoid on the starter.
 


Telling us the model would help. Saying you are working on a friend's MF is too generic to get you correct answers, unless someone happens to guess right.

I suggest that you drop down to the MF site, when you do, it would really help if you had the model(usually on a tag below the steering
wheel). There are many on the site that know what you are dealing with.
 
Total loss of power when under load is an indication of a bad connection,
partially discharged battery, defective battery, or shorted/locked starter.

Be sure the battery is fully charged and passes a load test, even though it
is new.

Start methodically checking for voltage under load. Begin with the volt meter
directly to the battery posts, move one lead at a time watching for where the
voltage drops.

Six volt systems require everything to be right, no room for error. The
cables need to be size 0 or 00, a common mistake is using automotive cables,
they are too small.

If the voltage drop is consistent all the way to the starter, try removing
the starter, see if the engine will turn. Sometimes the starter drive will
jamb in the flywheel locking everything up.
