Hey guys. New here, heard good things about this forum I see a couple charging threads already but I'd like a more specific 2nd opinion. A couple months ago I got a '92 Kawasaki ZZR250. I'm new to bikes, but I've done plenty to cars, so I wasn't shy of taking to her with some spanners. She's done quite a few K's (nearing 60,000) and shes a little rough but I did a big service on her - oil, valves, plugs, carb sync, etc. She seems pretty well maintained and runs good. I was given the workshop manuals too so I've referenced to those where I can. When I got her she was reluctant to start. Feeling the battery was shot I replaced it. Things were good, or atleast better for a while, but now she's running into issues again. Battery will gradually drain, and then she's not able to start. Runs fine when it kicks over though, had to get used to clutch starting her real quick. I suspect the Regulator/Rectifier is busted. To recap what I've done: - Replace the battery - Disconnect the R/R and ran the bike purely off the battery, testing the A/C voltage from the 3 wires from the alternator. Around 0VAC at idle, upwards of 60VAC around 4,000RPM+. Consistent across all 3 wires, so while the voltages are a bit higher than the workshop manual says to expect I think the stator is OK. - Tested DC voltage, just across battery terminals, with bike both off and running. Off is just below 12v (around 11., On is around the same, 11.8v-ish. Was expecting it to rise to atleast 13's. - Couldn't get the bike to start last night without jumpstarting. Rode for maybe 25-30 mins, turned it off. Would not start again - was reluctant to clutch start, luckily got it on the 3rd go. Once running, ran OK. - The pins in the plug between the R/R and main bike loom were pretty corroded. I took them out and cleaned them up, and multimeter shows continuity, but I'm concerned the plug is still in poor shape. - Removed R/R from the bike and tested it with a multimeter, checking for resistance outlined in the workshop book. I get, bizarre results, eg, no connection at all when there should be an ohm reading of some level. - The battery has been run low before, but still enough to bring up dash lights etc and clutch start it (until now). Put in on a charger a couple of times to keep it up. Since its also new, it should be OK. I'm fairly confident the R/R is the culprit, but as said, Bikes are not my forté and I'd appreciate someone else's thoughts The bit that gets me is why the bike does run OK once it manages to start. Got near to an hour's riding out of it last night, I would think that would be enough to polish off a battery were it running only from what charge it had. If I need to get another Regulator/Rectifier, has anyone any recommendations on which and where to get? Located in Sydney, not made of $$ though Also, I believe replacing the plug/socket on the loom would be a good idea. I'm good enough with a soldering iron etc, I'm not a total stranger to electrics. But I don't know my chances of finding an OEM connector, yet alone where. Anyone know what I'd be best to do?
