Sometime last fall I noticed my lights, all lights, were pulsating but they didn't do it all the time, everything else seem to be fine so I wasn't too concerned. Now they still don't pulse all the time but I can feel it while accelerating. Really concerned about going on a long trip. The bike has about 79,000 miles on it with a new battery that was installed this spring. The alternator is original and has never been touched.
Any thoughts or ideas would be greatly appreciated,
Thanks in advance

Re: 2004 GL1800 Electrical problem
The only time I've heard of pulsing lights on a vehicle using a standard alternator the alternator was at fault.Actually it was the brushes.A good "alternator shop" should be able to test first and repair it.
As always,double check your battery connections,dogbone fuse and connections on the alternator.
Should the little wire on the alternator be loose,it can cause problems.its the "get it going and keep it charging"wire.

Have you ever cleaned and tightened the main ground under the fuel tank.It's been known to cause some strange happenings.Then again all your battery cables should be cleaned and tightened,positive and especially the ground side.
If I'da known it would last this long,I'da taken better care of it.

The known problem with the ground is that Honda used thread lock on the bolt. You need to clean out the threads with a tap and die, clean the connectors, use a lock washer then tighten the bolt.Fatwing Chris wrote:Have you ever cleaned and tightened the main ground under the fuel tank.It's been known to cause some strange happenings.Then again all your battery cables should be cleaned and tightened,positive and especially the ground side.
