Hi i need help to try and work out what the part is or a replacement
I own a commercial slotcar raceway the computer system that runs the track is an old amiga the software is on a floppy disc
the computer turns on lanes via the F keys there is an interface that switches 70 amp relays on under the track the interface sends 13.8 volts neg to the relay to turn it on. Inside the the interface there are Two are ic's that control four relays each it. On one side one ic is not sending a signal to one lane only the other three are working.
My problem is that the person who build it can not be contacted and there is a heat sink on top of the IC so no number on the part can be seen.
The IC needs to switch between 11 volts and 18 volts dc on the Neg side i have at this stage no idea what signal is sent to the IC
All one side of the IC are connected to neg power wich comes from the track.
Hope some out there can sugest a part i can then trial on the bench.
Regards Carl
