Posted: Fri Oct 06, 2006 9:03 pmwith the starter cover removed gears out I tried to start it I got only 6 volts at the starter, it turned and the clicking stopped? battery is good! is the starter bad? or relay
Posted: Fri Oct 06, 2006 9:15 pmcheck the input and outpot voltage of the relay. corrosion of connectors common on these bikes
Posted: Fri Oct 06, 2006 9:17 pmalso, a bad battery can show 12v with no load, then drop rapidly with load. what is the voltage at the battery while trying to crank?
relay
Posted: Sat Oct 07, 2006 9:17 ammy rt 125 did same thing
1load test battery
2 jump big contacts on relay and see what happens
or try a different relay
here in the usa the relays on lawn mowers die and about 80% of the time
you can drill out the ribits clean the contacts and they work again
but the motorcycle ones are junk when you take them apart
3 contacts inside relay bad
4 yamaha number 4KD-81940-00 same as RT125 may fit other MZ Bikes
i paid $28usd in 2003 at a aftermarket atv shop

Posted: Sat Oct 07, 2006 12:10 pmI tried the load test and it drops to 6 volts... so hey that battery lasted me a long time
Posted: Sat Oct 07, 2006 12:58 pmSounds like a battery issue to me, last week i left work, started no probs, drove 4 miles to my mates house to drop off some tuning parts, chatted for 10 minutes, jumped on my bike and.......nothing! Battery died! Some clicking from realys, etc but not enough juice to crank her up. New battery next day, thump thump thump thump thump...brrrrrrrr.......sorted.
