I have been noticing my speedmaster is getting hard to start lately, does not seem like it turns over fast enough. keep at it and the battery runs down in maybe 5 minutes of starting attempts. If i hook up the 10 amp charger it starts right up.
I put the I put a new battery in less than 2 years ago. It spent the winter on a battery minder.
Putting a volt meter on the battery while it is running shows 12.5 volts. Revving up to 3000 rpm makes the voltage increase slightly but over 4000 it starts to drop. THe manual says it should be 14 volts at 4000 rpm.
anybody else have this? could it be a regulator/rectifier?
