Battery disconnect?

[jason.holland]

I just purchased a 1988 American Skier Advance. The battery was dead when it was purchased and I had to buy a new one. After install the power to all the electronics turned on without the key in the ignition. I'm having to disconnect the battery every time so as not to let it drain. Where should I start troubleshooting, or should I just install a battery disconnect? Thanks

I'd start at the ignition switch and look under the dash. Obviously something miswired or a hot wire is shorted where it shouldn't be.
