It took me a little while to install he new relays board I made with Rectifier Bridge Diodes before each of the relays in order to cure that problem I was having with the SFX module I had put together. I had to do a fair amount of shuffling things around on my stock dash to make things fit right. (left). You may recall from earlier posts when I was working on my Voice Projection Unit that I had the on/off button hooked up to a Step Relay that was located about where my new relays board is now. What I ended up doing was moving the Step Relay to the same location as the on/off button for the V.P. Unit and mounting it behind the panel that the button is mounted too (right). I also made up a small Rectifier Diode Bridge module with terminal blocks that I could easily wire up to between the on/off button to the Step Relay and mounting that in behind the panel as well. I like it a lot better now because when you press the V.P. button the loud click from the Step Relay is right behind where the switch is located and not on the other side of the dash like before, so in many way it makes more sense this way.
This is a much nicer relays board than my last one which was more for experimentation more than anything just to see if certain things were going to work the way I wanted them too. This new one I put together is better laid out, has more relays on the board and more terminals for the DTMF request from the Voice Box. The board is a little shorter than my old one width wise but a little higher height wise but given that it better made and has more on it I'll be able to work that under the passenger side of the dash a lot easier than my last set up. This new board also has Rectifier Diode Bridges built in before each relay so this will eliminate the problem I was having with switches that activated relays interrupting my SFX module when the relays were switched off. I'm a little fuzzy on how that works exactly but it works and it cured the problem so that is what counts. ;)
