I’m having trouble with the charging system on my Tecumseh oh180 I have in my max 2. The system is not charging the battery I’ve tryed narrowing down what the issue could be bought a new battery, went through the entire wire harness put a new inline fuse, checked the stator it read 123ohms, the only thing I haven’t checked is the regulator which I’m not sure how to check unless I buy a $180 regulator/rectifier tester which I’d rather not do if anyone can give me some insight that would be much appreciated
