Alpha Pi150 Engine Management System

[davidstanley]

Hi Guys, has anyone got an alpha engine management system installed on their motor. the PI150 model.

ive had a couple of components burn out internally that i need to replace, but the reference numbers have burnt off.

Any chance please, any one can remove the cover and read the reference numbers please. its for 2 items, they are:-

Transistor - TR15, and the Diode ZD1.

thanks for your help, Alpha have offered me no help and told be to buy a new unit !! great, can be repaired for about £5 !!

if they wern't the faulty parts what is to stop them burning out again????

see if there are any other parts on there the same as they try to keep the number of diffrent parts to a minimum??? most likley the same transistor is used all over the shop

thanks for the response. ive found out i had a ground fault which caused to dioide and transitor to pop. i thought myself they could be the same as the other ones on the board, but ideally wanted to double check. the ground fault i can sort.

alpha haven't helped at all, they just want to flog another unit.

any ideas? do you know anyone with an alpha unit?

cheers
