Hello all,

I am gathering information getting ready to install my Extreme EFIS with the RDAC MAP module. The manual says the Pin #8 on the DB9 is for power (12Volt) but I cant find the desired fuse (amps) size to install with it. What are you all putting in?

Thanks,
Scott

For that combo I'd put in a 2A or 2.5A fuse. I usually choose the slow blow types as the fast ones tend to "wear" and eventually blow even if current has never been exceeded.
