I have a Tom C electric on my gladesmen and at first it started blowing fuses. Now, after a few fuses the Lenco actuator is stuck and will not power up or down. Checked the power in and it is getting proper power. The up/down switch, when activated is only putting out around 8.5 volts which seems odd. Am I missing something easy here or could it possibly the actuator itself? Any help appreciated. Thx!
