[C320-list] Raymarine SPX5 Installation

[Jim Sweet]

Yeah, I have the voltages that I got from my testing and the tech guy @ 
Raymarine said it should be around 5 volts and since it showed .18v on one 
side he said that it was blown FET (field effect transistor).  I'll see if I 
can find a repair shop.  Thanks for the advice, gentlemen.

I agree with trying a electronics/tv repair shop. It's possible that the 
damaged is limited to this transistor, which is probably a discrete part 
that can have a new one soldered in place. Its probably a power transistor 
for the drive system if RayMarine said its a blown field effect transistor.

What I would do is take with you some info about the pinout/operating 
voltages of the unit so they can do some tests. RayMarine could supply some 
testing procedures for the tech.

Jim,

If it's a blown FET, any TV repair shop (assuming such things still exist in
your area) should be able to replace it.
