F2 Indicator problem

[royhall]

Hi. Have sorted the indicator problems. After an afternoon of playing with it and a few mods to the ground cables to the back indicators, the bike decided to tell me what it was.

When trying the indicators for the millionth time the rear left went out completely. Suspecting a blown bulb, I removed it to find the holder full of crumbly corrosion. On checking, both rears were the same. After a good clean with wire wool and WD40, the indicators work perfectly.

Nearly had me that one, and all the while everything was pointing to a bad ground somewhere. Just unusual that both sides decided to corrode at the same time. I have been using the bike up until Christmas, and been caught out in the rain a few times. Guess some water must have got in. If it goes again I shall just replace the indicators for new.

Thanks all for your help, especially Lobo who went to some trouble over it. Lesson learned on my part, was looking way to deep.

Cheers all.

Just noticed (shame I didn't earlier). Green1 gave me the answer and I missed it. Jeez, if only I had reread it I could of saved about a day in messing around. The spot prize goes to GREEN1.

Well it seems a day for indicator problems. Mine was a dry connection on the relay

I do get things right occasionally. 
Give the connections a good dose of ACF50 that's my new favorite product.

Got some of that, will give them a blast over.

what are you Mick, a salesman

Na I don't sell nowt 
But I did spray that stuff on a few iffy connections on the car and it now works.

Mick, do you think it will work on these two >> http://www.ebay.co.uk/itm/Honda-CB350-/151556079250?pt=UK_Motorcycles&hash=item2349723e92

They may be a little to far gone
Buy them for me and i'll squirt em.

The relay relies on the current flow to discharge the internal capacitor to get it flashing at the correct rate.  If you've got a bad earth,  that will cause this fault just like an open circuit bulb causes it to not flash.
I've threaded an extra lead from right next to the bulb, through to to the loom itself to overcome any resistance.

.... fantastic, well done; and glad you didn't pay out cash for some expert to fettle it.

By & large corrosion seems to be the #1 culprit with these electrical problems... forgiven I guess as the bikes all approaching 40!

Done the same thing Mike. On the rears the only route to ground for the indicators is through the rear light bracket.

I made up some cables that run from the bulb holders securing screws to the ground post on the back light. Soldered an eye at each end and joined the two together with a piggy back spade connector at the other, then plugged it all in.

The resistance reading on the meter dropped right down. Going to do the fronts as well when I get a chance.

I guess after 40 years of use a bit of corrosion also gets into the indicator mountings etc.

Good man.  Proper job with the ring soldered on.  It's the only way to go with 40 year old electrics.
