Back again.

Still not resolved this Starting issue when Hot.

I've taken Readings across the Stator 3 wires and there was a Variable figure of Resistance across them with no Resistance from each to ground, which i believe indicates a sound Stator or what is expected as readings.

However i did find that when i disconnected the connector block that it was heavily rusted and had signs of overheat (arcing) marks and discolouring on block and wires. I cleaned up wires and put them into in-line connectors.

Assuming that i had found the possible cause (non continuity of wire connections) i proceeded to run the bike for approx 15/20mins with radio and headlights on. then turned it off to start it warm..... Surprise surprise it would not turn over fast enough, really laboured ugh ugh ugh as it tried and tried.

Having read an article as a test somewhere, i tried to jump start it off a running car, this would indicate that the Battery was too flat to start it on its own. But still it would not turn over fast enough to start.

As an extra observation going along the other suspicion i have i checked out the ambient temperatures. Engine casing was between 30c/40c at Various points and the starter was 58c which was higher than exhaust silencer. my suspicion is that Engine/starter gets warm and expands to a point that it cant turn it over or that the starter contacts are heat sensitive. (as i say just a suspicion).

Candid Chris wrote to contact by ya email link. Sorry don't know how to get there on this message board.. It would be great if we could.

i've managed to maintain and repair all my different cars and motorbikes since i was 16 without having to pay workshops to do it for me, but this is really getting the better of me.

Any suggestions on what to check for would be appreciated.

Thanks Bryan

I have just put my Honda Goldwing GL1200 A1984 on the Road after being garaged and Cleaned up after purchasing it 2 yrs. ago after its previous owner sold it due to lack of use.

There was a starting issue with it where it really laboured to try and turn over or would not turn over at all. I took off the starter and serviced it checking the contact Brushes and pressure springs, I also purchased a new Battery. Even though it seems to be a slow turnover it now fires up immediately every time I press the button. I check it every couple of days and it’s not failed to start on first turnover.

I have taken it out a few times now for a local run and have found that even though it starts when cold without a problem it really struggles to turn over when warm and won’t start, it’s just as if it’s got a flat battery, but after it cools down for about 45Min's it then starts immediately.

Do you have any idea what it could be that’s causing this?

Candid Chris says:

Any bike that has sat around for awhile will have numerous issues, I'm guessing that yours is stator/rectifier related.

New battery- starts, runs(a good sign).

Runs for awhile and doesn't want to start/turn-over means the battery has weakened, it sits and cools and starts again.

Test the output from stator to rectifier and the output from rectifier to battery, one or both may be a problem.

Best guess

Additional Details

Thanks for your reply. Candid Chris.

What should the readings be from the Stator to Rectifier and Rectifier to Battery as you stated to check them.

I had already taken readings at the battery and was as follows:- 12.5v on static test. On fire up it dropped to 10.0v and back up to 14.0v as it fired up and on 2-3k Revs then when i put High Beam on it went up to 14.5v.

Don't know if this would give you any indication on your diagnosis
