Battery Upgrade!

[Downintheyukon]

So I bought about a month ago a 2011 gmc yukon xl with 70k miles, I went out yesterday to remote start the SUV and noticed is was slow to turn over but started everytime. I went to the local AutoZone and long story short said my voltage regulator was bad. So now for the upgrade! I decided to make sure it never slow started again and installed Mechman 240 amp alternator ( I wanted the 370 but my pregnant wife said no) and since I was messing around with the wiring I did the big three upgrade and dual battery upgrade. This is only my second post so please be nice but I am open to criticism. Please forgive the zip ties on the firewall I'm thinking on how I can clean up the double 00 gauge wires. What do yal think?!

If you did all of that for a slow battery, what did you do after your wife told you that you were having a baby?

Believe it or not I restored an airplane and am leasing it to a seaplane tour business lol. Thank you everyone for the kind words!

Cool, those are neat planes. There are a few aviators who are members here, I guess I'm an enthusiast.

A picture of your aeroplane wouldn't hurt. Come on...I know you have one. just like you have a picture of your wife and your baby when it comes.

I saw your handy work on the cables, dielectric grease and the immediate, deliberate solution to the battery failure issue and thought this guy knows how to re-engineer stuff for plan to fail situations. Makes sense now with your aviation background.

Can’t have enough residual power supply on these trucks if Mom’s cruising in them. 1, 2 or more kids means a lot of idle time when there’s appointments and multiple hops. Sitting in accessory mode on hot days will drain a battery quick when preoccupied with other stuff.

A higher output alternator is a smart move. During initial start up you don’t want the alt to work hard charging the system back up. It’s already running a gagilion other high load accessories. Yup, that’s the Seabee’s get it done way. Welcome from SoCal!
