gl1200limited no start

Postby clegg » Wed Jul 31, 2013 6:57 pm



Hi
Newbie and I need some help.
I just picked up a LE sitting in a barn for 5 years.
I have done a lot already to it.
I m not new to riding or wrenching. Got my license in 69.
I can always learn and ask for help.
So I'm asking for help.
The first thing I did was to put a replacement starter in. Some fresh gas and it started. Did other things and rode it around.
So I was going deeper to get a look at suspect air filter to replace-mouse has it chewed etc-I can also ask where to get air and fuel filters along w part numbers?
So I put conole back together and I have power to all lights horn hazards etc, bu no power to start it- ignition or engine spin. Also the lcd with nuetral light gear indicator and those other lights do no want.
I have wiggled lots of connections and checked fuses in panel and largefuse onright side ofbattery- all good.
I ll take any thoughts.
Thanks

I'll look into the schematic and see what and where you might be able to test.
Do you have a test light?

Here's the first test...right on the wires that come from the kill switch.There has to be 12 volts feeding it for the ignition and start button.You should be able to probe them right near the switches.

It also appears that the neutral lamp and other circuits are supplied by the "ignition"part of the switch.It's a black wire..It feeds fuses 1-5...Do they have 12 volts with the key on?

Thank you
I will test Monday
Another aspect of this surfaced.
I pushed bike out of the way to parked position.
I went by it a day or so later.
Having done nothing to it, I turned key everything was on and it started.
I walked away from it running, and it ran for five minutes, then just stopped.
Same as before.
Status quo.
To me that indicates a bad connection or contact somewhere.
Thanks again.

Using voltmeter and with key turned to full on position: no voltage on black wire at enginecutoff switch.
In fuse block the following fuses do not have voltage: meter, ignition , parking- all other fuses have 12v.

The black wire that comes from the ignition switch feeds those fuses.
If you can get to the back of the fuse block,you can locate the large black wire.It should have volts with the key on.
This is assuming that the 2 large red wires(when it quits) on the start solenoid 4 wire plug still have volts.
The red wire feeds the switch,the black wire feeds the fuseblock.
This is sounding like the ignition switch is bad...Confirm it first...When dead,probe the solenoid red wire for 12 volts(not the battery wire)...probe the large black wire on the fuseblock for 12 volts...The only thing in between is the ignition switch....

It's not too bad to repair them,but there are a few tricks.

I have also seen a corroded fuseblock,so this is a good time to inspect the insides.

When it 's dead,you could wiggle the ignition switch on/off several times to see if it magically comes back on...They do corrode.

Thank you for your help.
I rode it 30 miles Wednesday.
It was the bland wire going into fuse block.
A ok now.
Now Im onto next chase.
Unhappily it is not charging.
Po says stator was replaced 10 years ago.
I have fresh battery reading well.
When I rev at 3000 I get no reading across battery terminals.
I have checked- the suspect 3 prong plug has been removed hard soldered well.
So I assume stator is dead. What other test should I do to confirm it is absolutely the stator.
I'm not inclined to do an engine extraction.
Thanks

Do you mean that there is t a increase in voltage across the battery terminals?
At 3000 rpm,the battery should be getting around 14 volts.
There are a few tests to determine what is wrong.

I,ll test again tonight,there is no increase at 3000 rpm.
The battery runs down , as there is no charging occurring.
I can watch voltmeter on dash just go down.
It took bout an hour on riding stopping starting and radio to not crank engine.

Unplug the regulator.Check for the 25volts AC on the 3 yellow wires at 1000 rpm.
3 measurements,3 pair,3 wires.
No AC measurements to ground , just between pairs.
If OK.plug it back in and look for 12 volts on the little black wire.It goes on and off with the key.
If its there the regulator is dead or the contacts are corroded.
Post with more info.

Look at the plug to the left of the battery.3yllow wires there.They do corrode.solder them if necessary.
Search 3 yellow wires on this site.Theres plenty about it.
The wires can get warm and my regulator runs about 165* normally.

A more knowledgeable then w regard to electronics, friend came over
Stator is toast.
Wiring and connector at rectifier was burned several years judging by corrosion
Thank you for your help,
I guess I will be moving towards the poor boy, unless you have a suggestio!

I'm Ok with someone saying that the stator is toast if you also agree.
It bothers me just a bit that you mention that the yellow wires get hot.
Heat is developed when there is a lot of power being developed.
I just have to ask myself,if the stator is "toast",how the wires can get hot.

Remember,if the regulator were shorted out,if left plugged into the harness it will give bad readings on the 3 yellow wires.
When plugged in,I think they only measure around 11-12 volts AC.
The regulator must be unplugged or the 3 yellow wires unhooked for testing.

Sorry,I question everything and test twice.

No sorry to it
Thank you
I would rather replace reg
Only one yellow wire developed, a lot heat w key on.
We tested each wire and got 0 reading
Then went to unplug and saw the connectors condition.
We then unplugged it, I don't remember what that test was.
Between 3 yelloes we got 0 reading if I remember correctly.
We cut all three wires and did testing at which time, he felt the dtatr t

Message not finished
So from that reading he determined stator
I may take to anothr friend to determine
Unless what I said strikes you
I,m proficient in other areas
Om,s versus ohms
Thank you
