Re: Ingersoll 222 Can't start, power issue?
The fuse cannot truly be tested without the minimum of a test light. Your fuse is blown, most likely.
Listen, to all who may read this. You CANNOT own an older tractor AND not invest in basic tools that are needed to keep them going. I am not going to make a list for you, though. But here is how your needs will get met.
In this case, you need both a test light and a basic volt/ohm meter. The test light is easy a quick but does not tell you how good a connection.
Your next breakdown or maintenance job will mean yet more tools. Find something you need to do and it is difficult, there may be a tool that helps. That is how you end up with the tools and a well running older tractor.
But, in my opinion, it is not as bad as buying a boat. When you buy a boat, that purchase is nothing compared to the cost of owning and operating a boat,
