Re: Altronix 6062 Question

Sounds like you're on the right track. As to the value of the cap, that would depend on the current draw of the timer board, and the amount of time. I would try something in the 1,000 microfarad range first and take it from there.

We were doing a house rehab once and the alarm people used a RC car to pull wires in tight places under the house.
