dead battery?
« on: July 04, 2011, 02:03:17 PM »
I went for a ride on my 74 cb550 today.  after about twenty miles the engine started to sputter and backfire.  I switched the fuel from on to reserved and that seemed to help for about 1/4 mile then I just lost power.  Pulled over and I had barely a dim headlight.  I guess my battery isnt charging?  I just put a new rectifier/regulator on it.  Not sure what it could be.  Just replaced the spark plugs today also.  Any help is appreciated.  Thanks.

stock bike?

Have you measured the battery voltage?

Battery more than 5 years old?

It has a different exhaust and a new rectifier/regulator put on it.

Could be the rectifier, this just happened to someone one here and it ended up being cooked wiring to the rec.

Could be the battery too for sure, Get a DVOM and check voltage, if its still 12.5V or even 12 id check the wiring to the Rec.

You made me think about it after I cheered knowing someone else would like to know what these control freaks are up to.
 Every time any owner strips whatever precious Honda part the horrified purists parts go up in value. That's not the part that bothers them.
 What bothers them is they sat up late at night, their breast full of wonder and estrogen, unable to sleep, dreaming about their lovely darling and all her glory... and next thing you know someone else doesn't share their emotional deluge and their reaction is they must spread their mind museum as far as they possibly can, taking over as much of the real world as possible.
