I suspect my suburban heater fan is drawing heavy amperage when operating.
How can I make that determination?

Without a pile type meter-- you could check spec and put in a fuse just smaller until it blows . You can narrow it down pretty close. Often a drop of oil on each motor bearing will dramatically lighten the draw

You can find the fuse that feeds the fan, remove the fuse and put a DC
current meter in its place, read the current then switch on the fan and
note the difference. Use a meter that can take the full load the fuse is
rated for.

Dean:
The easiest way to check the amp draw is by using a clamp on ampmeter that works on DC. I have two, give me a call and I'll loan you one. If you want to purchase one, Klein Tools has a model for about $120.00 and will read up to about 400A.
