Per Jason's response, crimped ring terminals to GEA 24 wires and connected to shunt. Began fabricating shunt/circuit breaker cable. Called Jason with more questions regarding battery/main buss cable. Learned that the 6 AWG positive cables used in starter circuit may be inadequate. Jason will research further with Sky-Tech and also send along 60 amp circuit breaker to replace installed 40 amp circuit breaker, which was removed.
