Hi all,
I recently bought a Suzuki GS500 (02 reg) and I've been having problems with the battery. Initially I thought the battery was at fault however I've replaced this and still have issues.
If the bike is not used for a few days the battery has little charge left and when i go out for 20 miles rides it doesn't appear to be charging at all. Actually, the bike frequently cuts out towards the end of these rdies and then I can't get it started again due to dead battery.
I've followed the steps to check the R/R from the John Bates charging circuit test (and a bunch of other guides). Measurements are:
1. (battery) All off = 12.88 / 13.12. Idle (1200RPM) = 13.9. 2500 rev = 14.2. 5000 rev = 14.15 (However, this doesn't always happen, sometimes there is no increase)
2. 14.2
4. 60mv
6. 48mv
8. y1-y2 = 1.5 ohms. Y1-y3 = 1.5 ohms. Y2-y3 = 1.4 ohms
10. OL for all
12. y1-y2 = 65v. y1-y3=66v. y2-y3 = 65V
14. Red – y1 = 498mv. Red-y2 = 510mv. Red-y3 = 513mv
16. OL for all
18. y1 =514mv. Y2 = 512mv. Y3 = 510mv
Stator current (AC) at 5000 RPM between leads:
65v, 66v and 65v
These readings suggest that the stator is OK. According to the guides I'm using the readings for the R/R (14-18) are too low but they are all consistent.
The connection with the Red and b/w connects to the cable coming from the R/R and looks damaged/corroded. The yellow wires that also connect up to those coming from the R/R get fairly hot to the touch.
I'm not too sure what is going on here.
