Do you have the operators manual?? It should have a wiring diagram.

Belarus 420 Does Not Charge Battery
« Reply #1 on: October 07, 2016, 08:29:14 PM »
We have a 420 and decided to fix up a few things. When we purchased the 420, it did not charge the battery. It started ok, so we just ran it like that. A few weeks ago, we had the alternator rebuilt and purchased a new voltage regulator, but still no charging. So now I am trying to troubleshoot the charging system but I am having difficulty with the symbols on the alternator.  The symbols are: м, в, Ш and the fourth is three ~ on top of each other. There are two sizes of terminal but only one is larger...в.

Does anyone have an idea what these mean? Thank you!!
