Does it lock on at power up or when you start a game? If the former, it could be the pre driver or an ic controlling that. If the latter, check the switch.

Quoted from drocelot:

I went down and got some replaced the predriver and the driver transistor. Unfortunately its still happening....

Replace the IC attached to the pre driver, and maybe the one attached to that one too

OP
Quoted from drocelot:

So i have traced the wires and replaced all these components. When I run through the tests the Left Kicker will stay on and blow the fuse. Before it just did it at boot.
I've checked the switches, I guess the next is to replace the 7408 which is IC7
Thoughts ?[quoted image]

Try it with 2j13 removed, see if it still locks on in test.
