harbor freight spring compressor mods

Okay, I apologize in advance for my electrical questions. I am stumped by this stuff. When my 1993 KLR is running at about 2500 rpm the volts at my battery are about 12.6. When I rev it up to about 5,000 rpm there is no change in the voltage reading at the battery still about 12.6. I don't think this is enough to charge the battery. Shouldn't it be about 13 volts? Also when I ride it for about an hour the battery does not have enough power to start the engine. I've checked all the connections and replaced the starter relay (as it turns out I probably didn't have to do that). I've not replaced the stator or the R/R. Could this just be a weak battery? The battery was load tested and checked out fine. If I turn on the high beams, use the signals with the engine not running the battery reads just below 12 volts which seems okay to me. Have any of you folks had trouble like this? Also has anyone here purchased the aftermarket Electrex Stator and Regulator Rectifier? I hear they are great, but they are a bit spendy. I am new to the board, but have already asked quite a few questions and the responses have been great. You folks are very generous with your advice. Thanks.

Actually, my A13 shows about about 14.5V across the battery terminals when running 2,500 RPM or higher.

It sounds like your battery isn't getting charged, and the headlight et al. are draining the battery as you ride. Time to work through your service manual's electrical troubleshooting steps to find out why your battery isn't seeing any fresh juice.

Nope, I doubt it.

There were some quality problems with them a while ago, but they may have fixed them since then because I haven't heard anybody complaining about 'em in quite a while. Check the archive quicksearch for more info on the problems people had with them. -- Blake Sobiloff San Mateo, CA (USA)

Blake: Below you mention something about an "archive quicksearch" to find past discussions on the subject of the Electrex stator & regulator. Since I'm also interested in juicing up my A15, can you give me (us) some help on just how to do this search? Thanks. The search available on our "messages" page just searches the page, and I really don't want to go backwards page-by-page to find the threads.

Hmmmm? Not as exciting, but sounds like a good idea. Think I'll check it out. Thank you.
