Ron, your past luck is as mine. If you have any miles and/or years as I had on the original alternator, replacing the Regulator/brush assembly and the rest is original, well you get the picture. The only true way to test your battery according to what the Interstate Battery people told me, is to completely discharge your battery, then recharge at a low ampere input i.e. 1.5-2 amperes using an automatic charger that will reduce the input when the battery is completely charged. Then using a hydrometer test the specific gravity of each cell. The cells should test 1.275-1.300. The difference between each cell is to be no more than 0.025. My electrical problems are behind me, and what a good feeling it is. Happy Trails Beep Beep from Houston.
