odd occurance

I was out of town for 10 days so my vn750 sat for that time. When I started it to go to work it started very slowly...... but it started. I rode the 18 miles to work and stopped for gas. When I went to re-start, it was dead(not even a click)

I borrowed their battery charger and got the bike started, then took it to work. At work I put it on a trickle charger all day (co-worker had one in his trunk).

When I got home I checked out the charging system.... all checked out fine.

yesterday I put the bike in the shop for new tires, I told them what happened and had their tech check it out. they did a load test on the battery (OK), checked out the charging system (OK) checked for loose wires and connectors(OK)

so here is my question.... Why did it go dead? was just sitting for 10 days enough to drain the battery sufficiently to cause that?

I ride the bike most days so it doesn't sit much....any theories??

Do you know if the shop checked the fan switch?
It might have stuck on, which would've drained the battery.

well, the bike has worked fine for a week now....I get up this morning, go to fire it up and what do I get.... a very weak battery that cannot turn over the bike and a bunch of backfiring from the tailpipe.

I think either my battery isn't holding a charge or the rr is intermittently overcharging it.......any ideas out there??

I would take the battery and try having someone else load test it and watch them do it. Most auto parts stores can do it for you.

There is a some thing that is draining your batt. Check for lights that look dimly on when you park the bike. Also disconnect the bat and check for current draw while all accessories are off and key in off position. Also check your key switch. Hope this helps you.

Here's a dumb question... how do I check for current draw with the batt disconnected?

See if there is a spark when disconnecting one of the batt cables.
I am not really well educated on what meter to use but maybe some one here can help out. But one should be able to connect a meter of some type in series with the bat cable to check for current.
DC amp meter or DC volt meter.
