I grounded new dash instrument on the grounding strap that connects to the swingarm,noticed that my battery might not be charging-did I potentially blow/fry something?Fuses fine,recharged the battery-fires right up,little hesitant to ride it very far,battery around 13 volts+-,doesn`t seem to go down or up after running for several minutes...planning on riding it around town with cheap volt meter attached.Any way a battery can drain after key turned off?Checked hot wires I tapped into off of the fuse box-they`re off when the key is off,all "seems" well.... | ||

What makes you think it's not charging? There is only one large cable from the battery - to the chassis, there on the swingarm (at least on my S2; my S1W - 1998 - has a seperate ground wire for the updated voltage regulator). With the bike running above 2500 rpm (I think, maybe 3200) you should have 14.x volts at the battery terminals. Bikes don't charge at idle, you have to be turning some revs... There's also a stator test you can perform at the 3 pin triangular regulator plug, but I'd have to get my manual to tell you which pins to check. | ||

For one thing, a old battery can self-discharge when electrodes start to disintegrate due to sulfation. These tiny bits then fall to the bottom where they start parasitic current conduction between cells and eventually cause the battery to run down all by itself. But this self-discharge current is tiny and is probably not your problem if you ride the bike often. What I think you need to do is see if there is any current between the battery positive terminal and the cable that connects to it. If there is a clock on the bike, that will show up as a small drain, a few milliamps. If no clock, there should be no drain, zero milliamps. |
