Re: Re: [DML] Fan Relay Upgrade

Martin,

Microcontrolelr was a bit excessive for the fan relays, but couold be a very good alternative for the door lock module. After looking at the pictures in the vault of a stock relay harness i came up with the idea of having two relays and have one on a delay. After i came up with the initial design i alsmot laughed on how simple it really was, 3 small transistors, 2 resistors and a cap. I actually fitted the circuitry in project box the size of a keyless entry remote (not recomended, was a pain to build). I have not tackled my fan fail light yet, and really does seem that inportant to me (like the door lock light). Well it's a hot day out, lets seem if mine functions properly ;)

Happy Easter!
