Title: Motorcycle ignition ...Not AM related Post by: KL7OF on June 08, 2018, 03:52:36 PM I'm in Naknek Alaska. I have a 1987 Suzuki LS650 single cylinder "thumper". This spring It wouldn't start and in checking the ignition system I have narrowed it down to the "ignitor box" as Suzuki refers to it...The pickup sensor and the coil check OK..The normal thing to do would be to purchase a replacement..It is very hard to find a new genuine replacement..There are several "used but good" on E-pay but I don't like the odds...So I'm wondering if I can repair it myself...I suspect that the transistor is the failed component .Transistor has an "e" looking logo and the numbers D1071. All I have here to test with is a digital VOM. Any help would be appreciated. I wanna ride..... Steve

Google 'D1071 transistor' and you'll see all the info including where to buy.. GL Title: Re: Motorcycle ignition ...Not AM related Post by: KD6VXI on June 08, 2018, 04:37:28 PM http://www.ges.cz/sheets/2/2sd1071.pdf
Simple go / no go may work. Shows it as being a darlington config. --Shane KD6VXI Title: Re: Motorcycle ignition ...Not AM related Post by: KL7OF on June 08, 2018, 08:56:46 PM TNX..I ordered 2 of the 1071 darlingtons ..found a place in NJ that will mail them to me..(The preferred shipper in the bush)
We have 13 mi of paved road and about twice that in pretty good gravel road...Not connected to the road system..So I hope this will fix the ign..I am anxious to ride. 73 Steve Title: Re: Motorcycle ignition ...Not AM related Post by: KA2DZT on June 08, 2018, 11:15:06 PM What's the name of the supplier in NJ you ordered them from?

Bordentown is about 25 miles south of my QTH. I thought maybe you ordered the device from one of my distributors in north Jersey near Newark Airport. Good luck with the repair, hopefully it works.

I have to put the bike back together and test ride but it started and ran...Thanks ...Steve
