Drove the Elky to work today and on my way home (dark out at this time). I noticed that the dash and headlights were sort of blinking. Not on and off, just dim to brite. Like the voltage was fluctuating. The alternator is about 4 years old. This happened before from time to time. In the past I would replace the regulator and the problem went away. Tonight though, it was worse then ever....to the point that it was trying to shut off. The tach started going NUTS also!!! I would throw it in nuetral rev the gas a bit then it would be fine for about a half mile or so. Then it would do it again!!!! When I got home I replaced the regulator....still doing it.
Any idea's?????? Thanx
Brian

Have you taken any measurements? First thing to see what is happening. Measure the stud (B+) on the back of the alternator. When you measure it to ground you should see 13.5-14.7 volts. What do you see?

There is my other problem....I can't check any voltage since my tester got fried the other month. It was an old voltage/tach/dwell meter that was older then me that my dad used back in the late 60's thru to ???? I need a new one!!!!

Look over and wiggle all the electrical connections looking for a loose or dirty connection.

Buy yourself a new meter. This is the perfect excuse. For $20-$30 you should be able to get a digital autoranging meter that you just set to DC volts and test with. You can get non-autoranging cheaper but they're a big pain to use.

Maybe you're having problems with the brushes failing in the alternator?
