Hi folks,
quite new to the owners club, as you can see from my user name I am from Hartlepool, I am using a 1989 xj600 pre diversion comuting 80-100 miles per day and have used the bike in all weathers with out fault the bike show nearly 70,000 of which i have done 40,000+ in the last 3 years.
Last month it lost cylinders 1 and 4 having investigated the ignition system the fault was traced to the ignitor unit,could not get one from any dismantlers and yamaha wanted £500 for a replacement.So decided toopen cdi unit found two transistors in aluminium heat sinks, using a basic multimeter found one was showing no readings.Using the numbers on the transistors I found an equivalent in the CPC catalogue (www.cpc.co.uk) their code SC06850.
iT IS A DARLINGTON TRANSISTOR BDW42G
cost 76p plus postage plus VAT
I bought 3 for less than a tenner including postage
A little bit of soldering and Iam fully mobile again
Hope this helps somebody
