The amount of current those motors pull is quite high. Charge or replace the battery. If the battery was completely dead as you described you will probably have to replace it.
The other question is - what killed the battery? There is a chance (small - but possible) the jack controller failed and killed the battery.
The fuse for the jacks will not be with the other fuses. The current for the jacks is very high so it will be in line with the wire going from the battery to the jack controller. I dont know what they use in the Lance, so it could be a fuse, a fuseable link, a self resetting circuit breaker or a manual circuit breaker. Someone else on the forum could answer that.
One thing you want to check is to find the terminal on the jack controller that is connected to the battery and using your voltmeter see if you have 12 volts. If you have 12 volts you just might have a bad jack controller (which is a bummer!) If you dont have power, start tracing the wire back and find where the problem is.
