[Ducati] Starting problems - update

[Ronald Betts]

I have had problems in the past with Dielectric grease. Some connections are 
really sensitive to anything on the contacts. It seems that alot of 
electronics rely on certain amounts of resistance in the circut and even 
Dielectric grease can foul this up. I have gone back to the ole hairspray 
methode of insulating connectors and connections. Make sure things are clean 
and snug on the connector and spray around the connector. Aqua Net is my 
personal preference if you can find it.It also cleans up with a little water 
or alcahol and it dries fast on application. Use moderation as you can get 
the stuff inside the connector and you'll be back to square one.



Peace...Ron"Desmohead"Betts 95 900 SP
I've learned that I don't suffer from insanity, I enjoy it!
