voltage readings

[mhill316]

I have 84 evinrude model e60elcre and i'am looking for the voltage readings i should have on the terminal block at idle. also should the readings increase when the rmp's are increased.
red - ?
yellow/blue -?
yellow/gray -?

Thanks, mike

Re: voltage readings

Put the voltmeter on the battery terminals with engine off, then with engine running. The voltage on the terminal block is AC.

Re: voltage readings

When i check voltage at battery i get 12.3 not running and 12.8 with it running.

Re: voltage readings

Good, your rectifier is at least partially functional. Now see what it reads at around 2000 RPM with some load on it (lights, radio, GPS, etc.) to see if both sides are working. It should increase.

Do you have a tachometer connected?

Will check that next. I was only getting around 9v ac on the 3 yellow wires, seems i've read that you should get alot more than that. Yes i have tach and it works fine.

Re: voltage readings

The yellow wires are the charging system for the battery and the pulse for the tach.
