Are there any cheaper alternatives that are fully functionalthat do not
have to be build?>When I looked at reasonably priced multimeter options
last night I could not find any that
were not limited to 10 amps, beside the above two.
Look for a homebrewed shunt that you can build yourself, then you can use
your 10 amp multimeter to measure the higher loads.
A few results of a quick search:
Another approach uses a wire of known resistance, measures voltage drop
across it, and dividing by a factor to get amps.
This thread may be helpful:
Here is another thread that has some good answers for exactly what you are
Anyway, as you can see, there is plenty more out there than this list, if
you need to do more looking than what is here. I think you can take it from
here, now! <g>
