Power outage

Post by peterstoddart »

Took my GL 1800 in for an MOT. The examiner left the ignition on for a while and the battery went flat. He gave it a boost to get it started but it cut out riding home after only about one mile. All of the dials cut out just prior to the engine dying. We got it back to the garage after a jumplead start but it died again when I got back to the garage. They thought it was the battery but they told me today that it starts under the power of the battery if is left for a short while so they do not think it is the battery. Thoughts anyone?

Why has the charge rate not been mentioned, surely that must have been tested. If instruments fail before the engine, it is a clear sign of undercharging.
If at first you don't succeed, hide the evidence.

I had two bikes do the same thing. One 1500 the other 1800. Both bikes would start and run for a short time then instruments would shut down and soon the engine would shut off. Both bikes had to have alternators replaced.

I wonder,does the bike have a seperated fuse that comes off the alternator.?Besides the main fuse.Id test probe the alternator wire itself to see if it has 12 volts on it and then 12 volts on the trigger wire with the key on.

I am going to assume you don't have a voltmeter installed on your 1800, with that said, start your bike and check the voltage, it should be greater than 13.2 volts. Check fuse 14 (10A) this is the ignition sense fuse, if this fuse is blown the regulator in the alternator will not turn on.
