iresqu1 Posted June 25, 2014 Share Posted June 25, 2014 http://www.electrosport.com/media/pdf/fault-finding-diagram.pdf I don't know if this has been posted here before but it is a really good flowchart to help you find what is causing your problems with your charging system. Very thorough and easy to follow. Should be a sticky if it is not already. Link to comment Share on other sites More sharing options...
Member Contributer mello dude Posted June 25, 2014 Member Contributer Share Posted June 25, 2014 ^^^^Hi dude - Yeah that has been posted plenty of times. - It seems electric charging issues are the number one sticky wicket of vfrs. There were(are) so many what to do threads out there and a multitude of divergence of how to, and not much of it really saying in a strait forward way on how to debug. Well mello dude OCD whackjob engineer (occupational hazard) jumped out and it got old, so he compiled what is supposed to be a step by step and its below. It's from the KISS school... keep it simple stupid. - Somehow it got named "The Drill". --- It has helped lots of guys. If you go through the tests and write down the numbers, most cases the obvious answer is there. Sorry for your electrical troubles. Well, looks like you gotta do…. “The Drill.” Go through all your connectors for burnt leads, dig deep. Crispy wires? Not good. Your gonna have to fix that! Then---Go through this starting point quick list. You will need a multimeter too. Steps: - Recharge battery overnite - then to take it to Autozone, Batterys Plus or similar to load test. -- Good? Bad? – An iffy battery can fake you out and act like a bad R/R. Buy new if needed. - With good battery fire it up, warm up for a minute or two. These are R/R quick checks--- --- With voltmeter at battery get voltages -- idle volts? 5000 rpm volts? What’s the numbers? Should be in 13ish min idle and in 14s at revs. If in the 12s at idle, try at 1900 rpm. (It’s not unusual for the system to be in discharge or no charge at idle.) - Check stator - 1. Pull connector apart. Set meter to resistance. Check pin to pin stator side, 3 yellow wires, A to B, B to C, C to A. What’s the numbers? 3 separate readings --Should be less than 1.0 ohms. (Engine off) - 2. Check continuity from each A,B,C pin stator side to ground, -- -should be infinity - nada nothing. no continuity. -- 3 separate checks. (Engine off, again connector is apart) - 3. Crank it back up. Do another pin to pin thing, but set meter on AC volts. idle and 5000 rpms. What's da numbers? Should start 15 -20ish and climb 50ish and more. Again – 3 readings stator side connector and still apart. - Repeat hot. This quick list will catch the obvious stuff, but if you need to dig deeper check this chart. (Some guys like this chart, my taste, I don’t care for it.) http://www.electrosport.com/media/pdf/fault-finding-diagram.pdf Pease bro Link to comment Share on other sites More sharing options...
