Pickup Troubleshoot help

[Cela420]

Hi all,
So my Lakland skyline 55-05 hasn't been working for awhile now and I started to try to fix it. The issue is that the signal won't make it to the cable. I've checked/replaced the battery and that didn't seem to be the problem. When I was testing the circuits I had one from the input to the part under the pickups, but when the pickups are on there's no circuit. So my question is, is it safe to say my pickups are the issue?

It’s unlikely that both pickups failed simultaneously.

The pickups can be tested separately from the preamp. They can be connected directly to the output jack and tested passively.

My bets are on a dead preamp that will need to be replaced.
