Go after the K1 Relay.

Same thing can happen to Crown SP 3000, 3400 & 3500.

Responding to the TSP not starting: I would suspect either your key switch or K1 relay. Most of the time if you can turn and hold your key switch to start and it starts up fine but shuts off when you let go it is a bad K1 relay.

Want to pick your brain Triggs... I have a TSP6000. When I key it on access 1 will come on, but as soon as you let go of the key it goes off. No blown fuses. Key switch is working as it should. I'm pretty new to all this and LOVE electrical components... when all you have to do is swap them around that is lol. Any help would be greatly appreciated.
