I have been working on my bike(79 550E) for the last 2 months, started with a carb clean, working on removing some rust etc. I had to go slow because of the work and family, just work on it in my "SPARE" time. well I finally got it back togetherand my tank painted so I was ready to start it up and work on tuning the carbs and get it back on the road.
New problem...
I re-installed the battery but the bike is completely dead. I turn it to on and there is no sign off life, no horn no lights nothing to indicate that it's getting juice.
Tested the battery and it's good. Before the work the electric system seemed fine. I don't think I messed with any wires. I did clean the stator cover but was pretty careful.
Any ideas?
Just another problem
 
Test to see if you're getting power to the main fuse and the ignition switch. A wiring diagram and multimeter are going to be your best friends now.
 
This has happened to me twice. The first time I cleaned the fuse block and all was well. The second time I pulled a "good" fuse and it crumbled in my hand.
 
Silly question, but I'll ask it anyway...is the battery good? And charged?

OK, so that was two questions, but you say you have been working on it "for the last 2 months". I have never seen a battery that will charge itself while sitting on a shelf. They DO, however, discharge. 2 months is plenty of time for it to go dead. :oops:


.
 
I checked the battery and it's got a pretty good charge, enough that I think it would at least give a bit of life to the lights or horn, something. The battery was only a few months old when the bike went under the knife.
I think I am gonna have to go through the whole electric system, bummer.
just when you think your almost there, another step back.
Any ideas on how much I can sell a non running 79 gs550e for?
 
Time to sit down with the wiring diagram and make sure the electrons are getting where they're supposed to go.

Take it a step at a time, starting at the battery terminals. Confirm the voltages are what you expect at each point. It's pretty straightforward.
 
I just encountered this problem with my 80 550e. After replacing the carb boots, I had nothing but the neutral and oil pressure lights. It wound up being a grounding issue. Apparently I had not gotten the ground wires back exactly where they were.

I know its way late but thought I'd post this for future searches.
