Triumphs :rolleyes:
A few days ago the bike (Daytona 675) failed to start (no juice in the battery). I've recharged the battery and tested the following:
1) unplugged battery: 12.9V (battery was charged and bike started a few times yesterday.
2) battery on bike, ignition off: 12.6V
3) ignition on: 12.2V
4) bike running @idle: 12.25V
5) bike running @5k: 12.6V
6) 3 phase AC @idle (RR unplugged): 21V, 20V, 17V
7) 3 phase AC @5k (RR unplugged): 45V, 60V, 48V
8) 3 phase resistance (bike off): 0.3 ohm
9) 3 phase resistance to ground: 0.3 ohm
10) leakage current: 1.3mA (bike has no alarm)
Looks like the RR is at fault as it's getting the 3 phase voltage and not converting it.
However, I am baffled by:
9) 3 phase resistance to ground: 0.3 ohm
6) 3 phase AC @idle (RR unplugged): 21V, 20V, 17V
7) 3 phase AC @5k (RR unplugged): 45V, 60V, 48V
Why despite what looks like a short cct to ground am I getting roughly the correct voltages?
Also the diode test on the RR didn't show an obvious fault.
Any ideas what's at fault?
Cheers
