Subject:      Fixed ISC-Unit! But, everyone.... ?
Content-Type: text/plain; charset="us-ascii"

Hi list,

Week before... I dissected Idle Stabilizer Control Unit (VW 251-907-393B). The one condenser and one transistor were burned. I don't know why part was burned. I ordered that parts to the friend. He is the engineer of SONY. He delivered that parts to me yesterday. I attached that parts to ISCU. Work was finished in 10 minutes. Westy's idle is stable now (about 950rpm). But, when A/C works, transistor becomes very hot. Which Westy has this heat, too?

I don't trust this unit. Because, I don't make the cause that unit was burned clear.

Anyone can explain to me the symptoms of this transistor ? Anyone have the Semiconductor diagram of this unit?

I want to search this unit. ISC valve (025 906 457A) is new. If I can't solve this problem, I will attach CPU-Cooler to the transistor. I am familiar with Westy's troubles little by little. It's Fun!! (^_^)
