Regulator rectifier problem

[The Lone Rider]

Well.. blew a battery.

According to my maintenance manual, across the terminals of the volt reg rec the resistance is suppose to be from 500 - 10k

It is not. So in comes new reg rec - there are several websites that say the have one for my bike - 1994 VF750C

I phoned budget spares in ChCH today, they said they have one... however it is labeled as a reg rec for a VF750F. They assure me it is all the same

The only visable difference is needing to change around the plugs to fit my bike - put on the plugs from old rec

And the place where the bolts screw on are raised (good thing in my opinion.. I had to get a lady friend to undo it for me as my hands are too big to get into the small area)

And the new reg rec has an extra "black" wire that budget spare says doesnt matter - just don't connect it to anything when changing the plugs.


Lastly.. when I test the resistance on the new reg rec... well I set my multimeter to 2000K which is suppose to be in a resolution of 1kOhm... and multimeter gives the 1 notice - meaning it's over the measurable amount it is set to. I suppose the 2000k means it can measure up to 2000k max.. and the resistances are up to 10kOhms

Anyway.. any advice and what not would be helpful.

The sooner I get the bike going, the sooner I can score with this chick in Ashburton.. er I mean ride to Ashburton.

Try swapping the leads of the multimeter around.

When you are measuring the resistance of the regulator rectifier you are measuring the resistance across a diode so it will only show a reading with the current going one way and it will show a infinate resistance the other way.

Better yet just use the diode tester of the multimeter if you have one. Just get the diagram for the regulator rectifier and make sure that the current flows the right way across all the diodes and that's what you really need at the end.

Hope this helps. If you need more explanation let me know. Might be able to draw some pictures up but too lazy right now.

Nah it's not the leads, I've already tried that and the manual for the bike specificially says which lead goes were.

I have a suspicion it's just my MM is rated to measure up to 2000 ohms.. my rect is suppose to do 5000 to 10000 ohms.

I am taking it into work to see if they have a better MM
