First off that is not how you check your "charging system" not a magneto! on these bikes you have a Stator that is in the LH side cover on that engine and you need to check the windings for continuity and for short to ground. I would consult a local dealer for voltage output test spec's on the stator. next is the regulator rectifier, this can be tested with a meter and again consult your dealer.

when checking battery voltage while running it is common to have to bring the engine up to a higher speed than idle when testing the charging system, I would advise around 2500~2800 rpm and expect voltage to be 13.5~14.5 volts.

Battery alternator


I should tell you running the car with the battery disconnected can cook the alternator and the engine computer. The alternator needs the battery in the circuit to keep power flowing in the right direction.

Took battery out of my 1993 buick riviera,put back in now starts then dies


how did you disconnect the battery, pos first then neg ? or neg first then pos ? try starting it and after started, hold your rpm at 1500, for about two minutes, then if still running, drive it to get to.speeds of 40 for about 15 minutes, this is to relearn if not, disconnect your battery, take the pos and neg cable and touch them together and hold for about a minute, then Connect them back, neg.first.then pos, then follow steps above to.relearn.

Run and them dies


I found a vacuum leak on the carb base gasket by spraying carb cleaner around it. Then it would stay running while spraying. I replaced gasket but it still run and died. I was told to clear all codes in the computer by disconnecting the battery cables from the battery then hook the pos and neg cables together for half an hour. Then I hooked the battery back up and started it up and it ran better than ever. I guess unless you clear the codes the computer reads theres still a problem even though you fixed it.

I have a suzuki boulevard c50. The battery died over the winter and had to be charged. It has failed to crank 2 times since then. I jumped it off and rode for about 50 miles home after turning it off it...


It sounds like it is time for a new battery. While the regulator could have been damaged during the jumping procedure, the symptoms you've outlined still point to a bad battery. Motorcycle batteries do not fair well from a complete discharge. Sometimes removing the all of the acid and replacing with new acid will provide another year of service, but not always.

My reasoning for the thinking it is the battery is because of it not being kept charged over the winter and it was working fine before then (charging system usually does not get damaged from non-use). If the bike died when you removed the cable while it was idling, this would suggest the battery as well as a magneto based charging system is very weak at idle and relies on the battery to supplement it during periods of idle. To test my theory, jump the bike off, rev it to 1200 to 1500 RPM and disconnect the jumper cable. If the bike continues to run but dies when you let it idle, then the charging system is functioning and the battery needs to be replaced.

2003 Hyundai Sonata starts when cold and dies after warming up.


Wiring problem or the ECU (engine control unit) is defective. Try this, disconnect the battery cables from the battery and short/touch them together for 30 seconds (do not do this if connected to the battery). Then, reconnect the cables to the battery posts & see if that fixes it. If it doesn't, then there is a wiring problem associated with the cam pos snsr or the ECU has gone bad.

My son's 96 grand cherokee kill's the battery when engine is shutoff and also when running the volt meter will be o.k. for a bit and then nose dive to 0 volts. had alt. checked o.k.. seemed to start acting...


start the vehicle up and unhook the pos cable from the battery if it dies its going to be a bad alternator or the battery has gone bad.one sure way to know if its the alternator is to un hook the pos cable while the car is running.they can test good even when they arent.
