I've gone through a couple batteries on my '95 VFR750 recently, so I've been wondering if it's just a coincidence or if I have other problems. The regulator/rectifier seems to be charging the battery fine, starting at close to 14V at idle, and quickly maxing out at 14.8V when revved just a little. So the output voltage is neither too high nor too low, at least whenever I've checked. At present, I'm thinking either my starter gets sticky at times and exceeds the CCA rating of the battery (180A), or something is happening during rides that causes the R/R output to be too low. Neither is easy to catch, so installed a 50A/75mV current shunt on the negative terminal of the battery to monitor whether the battery is being charged or discharged. I had the shunt installed differently earlier so that I was measuring current flow to the bike (sourcing from the battery and/or R/R), so I was able to gather a few figures on total current draw (not just in or out of the battery): * Headlights take around 9A to run. * Cruising around took about 12-14A. Turn signals and brake lights would add 2-3A to this load. Higher RPMs would push current draw toward 14A, I assume to run the spark coils. * The starter would usually spike 100-150A briefly at the start of the crank. * If I cranked the starter extra long, even after the bike had started, I would see a draw of around 30A. After moving the shunt inline with the negative terminal of the battery, I noted a few other figures: * Cranking the ...
