This is the big brother of the 20 Amp tester. It can be used with Maxi, Standard and Mini blade fuse holders and can measure up to 80amps. It has a hold function as well as a peak current mode. As even the best multimeters only read up to 10amps and most mid to larger bikes will charge at quite a bit more than 10amps this is the perfect tool.

If your bike doesn't have a fused charging output from the regulator/rectifier it is worth fitting an in-line fuse holder, not only for safety, but also as a port to easily test the charging current. We've been trying to think of a way to overcome the difficulty of testing bike charging for years, and we think that this unique solution is sheer genius.
