Cooking the battery
1995 CBR quits running in the middle of nowhere, no voltage, very dead, very hot battery,hitch hike 25 miles to Wall-mart & back, replace battery and get about 75 miles and bike dies again. Call home for the truck.
Find wires and connector at voltage regulator burnt brown and crispy.
Install Honda repair connector and solder in wiring harness and replace regulator with a cheap ($45 u.s.) internet unit.
Check system with volt/ohm/amp meter and all is OK.
Two-hundred miles later the bike quits again, no voltage. After charging the battery and checking the charging system I find that the regulator is way too hot, so hot that it has cracked the resin. The cheapo regulator didn't pass the ohms test and another one was sent, no questions asked.
This regulator lasted six-hundred miles. The bike started running very bad and when it was shut off it had no voltage in the battery which was so hot it couldn't be touched for twenty-minutes and smelled bad from the boiling sulfuric acid.
A new battery got us home without a tow job.
The alternator checks out ok with an ohmeter per the test in the workshop manual as does the wiring but again the regulator fails the test.
Is the problem just the cheap regulator or is there another problem causing all this.
Thanks

RE: Cooking the battery
sounds like you need to replace the cheap *** regulator. alwaysremember the 3 main parts to your electrical; battery,reg,stator. if one fails it causes the other 2 to go bad. id really re-check your stator because after having the other 2 fawked up id almost gaurantee the stator is messed upas well .
i should also note that if your stator isnt functioning properly its making the bike run soley on the battery. normally the bike runs off the stator and the battery is used for our electricals (lights, gauges etc). the reg in the process of being connected to the battery when it [the battery] is the only thing powering the bike, gets fried.eventually the battery gets fried as well and like you've experienced. replace 1the next domino fails and its a vicious cycle and you dont want to get stranded when this happens
