Tester Question

[bipolarnut]

This may have already been covered in a previous post but I could not find it.

When my 1971 Evinrude service manual says High Ohm scale what should my digital ohm meter be set to likewise what setting for Low Ohm Scale.

My tester has Ohm settings of 20M 2M 200K 20K 2K 200

Thanks

Re: Tester Question

Your digital meter is much more sophisticated than the analog meter used in the manual. On yours, 200 would be the "lowest" and 20M the highest. So 200 would be used where they say "lo ohm". The rest would be selected according to what the expected resistance would be. If you select the wrong range, no harm you will just get an overload reading, usually something like OL.

Be aware that if you are speaking of testing diodes and rectifiers, your digital might not be able to do it. Mine won't either.

Re: Tester Question

I have been testing diodes and rectifiers also my stator and I get strange results. I have a 1971 100hp evinrude and when I test the stator on the motor according to the manual I set the meter on the 200 ohm setting and I get a reading of 1.1 this is the same reading I get when I test the stator that the mechanic replaced because it was bad. So either they are both bad or both good but they read the same but different from what the book says.

Test each lead from the stator, to the stator ring itself, and see if it is going to ground. I have rarely ever seen a charge stator go bad.
