Wiring relays

[JamesO]

I've finally made it to the relay point of this bluesmaster build with Brandon's chassis and board set. I ran a few searches and had trouble coming up with information. If anyone knows of any threads that deal with reading the relay section of schematics, working with Brandon's relay boards, etc, would you mind passing them on?

I was in the same situation a while back and found this thread to be really helpful.

Sitting down with a relay and batteries was the most useful thing I did, to get my head around relays (as mentioned by Brandon in the post, I believe)

Best of luck.

Cheers, Paul.

70s amps, NON-HRM amps, and HRM amps all have slightly different relay wiring.

Search for schematics for #40 f, #124 and ODS-102-HRM.pdf to see the three different wirings. A Bluesmaster with "Megaboost" will also have a slightly different wiring also.
