I have an 85 GL1200 Interstate - no fancy accessories - even took out the radio. Two years ago and about 12K miles ago, I replaced the stator as part of a winter rebuild since the bike had been garaged for the previous 8 years due to bad stator. I replaced the harness with one recommended here on the forum and thought I'd be good for a long long time. BUT! I stopped during a recent ride and upon attempting a restart, there was insufficient charge to turn the starter. Fortunately there was a hill sufficient for a push start. So of course I ordered a battery - thinking maybe two years was all I could expect to get out of those little batteries. While waiting for the new battery, I gave the old one a good charge and even though its starting umph seemed to wane after a couple days, it's performance made me second guess my $150 purchase of a gel battery. This morning I installed the gel battery and it tested at 13Volts. Then I rode the bike about 90 miles and tested it again - now it's 12Volts and the restart seems to be weak. Is there any other explanation for that other than stator? How can I test the stator? I can recharge the battery between short rides, but I was hoping for a long tour this summer. Any insight?
