1985 goldwing GL1200L LTD

Postby BornBAD928 » Thu Jul 07, 2016 5:07 pm



Hi everyone, I have an issue that is even stumping the repair shop. After a new starter solenoid, starter and rectifier, they finally got the bike to run but it stops and won't restart until it has sat for a few minutes. The shop has no ideas and they are even trying to ask Honda what they say about it so waiting for Honda to reply so I thought I would run it past GD forum, so what do you guys think? I have little or no bike mechanic knowledge so for me it's the shop or you folks here when I need an answer, collectively I think owners tend to have more experience therefore more knowledge which is why I am asking here. As an after thought I am posting a few more details.....it is a 1985 Honda Goldwing GL1200L LTD with electronic fuel injection, changed the starter solenoid, the starter, and the rectifier, the rectifier has 2 connectors one long and one short, the short one had 2 wires, one of which was burned right off the connector but the connector itself was fine. Don't know if this info will matter but just felt that I should have added it so I did, thanks again for any input

Pulse generators getting hot and failing, hence no spark? I thought the FI versions had a diagnostic computer built in?

my understanding was that the CDI spark ignitors needed replaced which caused no spark after replacing them it would run then die and not restart until it sat for a few minutes then same thing....

Check out your fuel filter, it may be clogged, also check the fuel pump, it seems you are getting starved for fuel.

BornBad......What was the final answer to your problem? Was it just a clogged fuel cap, or what??????

if the 85 fuel injected model is almost the same as the 86 SEi, it should have a computer, and it should be mounted under the trunk. you'll need the electronic service manual to pull up the trouble codes on it to be able to diagnose any electrical problems.

Just thinking here that something is heating up and then failing. Don't think the starter, starter solenoid and rectifier-regulator would be affecting the bike as you mention.

With a bike this old, changing the fuel filter is good maintenance as is making sure that items such as the gas cap vent. Also check the storage tank that is just to the right of the shifter foot peg. This has to be emptied every now and then as it is part of the air breather filter system.

Here is a link to an OEM parts fiche:
http://www.partspitstop.com/oemparts/#/ ... l-ac-parts

A few items that are affected by heat build up are the pulse generators, Ns - crank pulse sensor, and the coils. Not much on the forums regarding CDI spark ignitors, but not out of the realm of possibility.

As roadwanderer has stated you need to look at the trouble codes (if any) on the computer under the rear trunk.

Lots of good help/info available here. Inspect/fix one item at a time and run the bike, process of elimination. Don't do too much at once because you will not know what corrects the issue if you stumble on it.

If you don't have any manuals, send me a PM with your email and I will send some docs your way via wetransfer.

We like pictures if you have them as well.

Good luck.

Cheers

Sounds like a crank pulse generator to me. It's located under the timing belt cover and reads off the crank pulley. Seems to be a very common problem with these bikes especially as they get warm, I had an issue were mine was intermittent because of corrosion on the actual metallic part of the sensor, something that a little bit of steel wool took care of. On the LTD's it's a single sensor whereas on the carb models it's a dual pickup sensor. The sensors aren't available from Honda anymore but I've heard of guys using the sensor out of a carb bike (still available from Honda I believe) and modify it to only using one side of the two sensors.

if your going to use a dual sensor like i had to, cut one of the sensors off leaving enough room between the 2 sensors, tape one side of the wires up and use 1 of the sensors. that way if you need to, you can use the other sensor if you have to change them.

A fellow I corresponded with who is in the interior put an Ns sensor from a 1500 on his SEi, P/N 30300-MN5-003 ($145.39). Used one of the two and now has a spare he would let go.
