Brand New here so HI to start. Just got a 1990 550sx Kawasaki. Nice rig at a good price. Seller claims to have just installed new battery prior to my purchase. It dies after 4-5 of sitting. I trickle charge for 2-3 days and it holds for about same. Ordered a new Odyseey pc625, as I had good luck with those before. Just wondering if there is a quick way to check the charging system on my new ski though? I know those lil' batteries like the seller installed aren't very reliable, but just want to make sure that the ski is functioning properly. Will a volt meter show difference between running and not? I am guessing it should show more volts once the motor starts, correct? Thanks in advance, and I look forward to these forums!!
