A few years ago I tossed the clock on my Aspencade in favor of a voltmeter off an SE-i. I have a watch.
This spring I had a small problem with power supply to the ignition and found the red spade terminal connections on the starter solenoid a bit dirty. I chalked it up to sitting for months on end and after plugging and unplugging a few times, the problem corrected itself.
I've also been noticing the charging system putting out less than usual. It was falling down to 12.8 at idle. I know, some guys think that's acceptable, but I don't. It's always run 13+.
Today I decided to tackle the problem before heading for California next month. The spade terminals on the solenoid were crusty, so I finally broke down and did the main fuse (dogbone) bypass modification and installed a 30 amp in line fuse holder. With very interesting results. The terminals had enough resistance to clamp the amperage returning to the battery, resulting in a lowered charging capacity.
Keep in mind, I have a stock stator and regulator. I performed the mod years ago to take battery voltage to the regulator, rather than sensing off the system voltage. The voltmeter reads actual battery voltage and is accurate. Readings at idle and 3,000 rpm show the regulator is functioning correctly. What a difference!
