#MOUNTING BATTERY ISOLATOR RELAY ON GMC 2011 HOW TO#
Read on to see why you need an isolator and how to install one. My best guess is the unknown negative wire on the left battery is going to a ground elsewhere, maybe the frame? Not sure what the unknown positive wire is. Adding a smart battery isolator will let you charge your batteries from your vans engine. These are spliced into the battery cable, and flipping the mechanical. I'm just not sure what I'm looking at with the unknown wires coming from the left battery. It has a continuous rating of 175 amps and a surge rating of 1,000 amps and is sold with and without the mounting plate. The winch is also hooked up to this battery. The right battery also has a ground coming from the negative terminal, and positive is wired to the Fuse Relay Center box. Again, I can't really see where this terminates. There are three wires coming off the positive terminal - one to the alternator, one to the fuse box marked "Fuse Relay Center" on the driver's side, and one to somewhere towards the front of the engine block. First, locate the starting battery in your engine bay. The negative terminal on the left battery is grounded, and a second wire from the negative terminal runs to somewhere near the exhaust manifold on the passenger side - I can't really see where it terminates. Part number is somewhere in the Chi-town 4x4 link in my article.You must be registered for see images attach Only other advice is to put your fuses as close to the batteries as possible.Īnd then as mentioned get the GM diode alt-s fuse to boost alternator charging voltage slightly to be a better fit for AGM charging profile. You'll need a hydraulic crimper to get the lugs on the 2ga wire properly, do not solder, and the 3:1 marine adhesive style heat shrink is a must. As long as you're driving each day to top off the house battery this will work great and keep your starting battery untouched.

I see you're running both batteries as matching AGM type so that's good too. KeyLine Chargers 12V 140 Amp Dual Battery Isolator Voltage Sensitive Relay (VSR) Pro Dual Battery Kit : Buy Online at Best Price in KSA - Souq is now. Group 24 AGM will run your fridge all overnight even if it's stupid hot out and fridge is empty. You don't need the switch from the Antman diagram if you just run the PAC500 switch from a keyswitch source in the fuse box, you should simply use an "add-a-fuse" to anything keyswitch power. What part of the West are you headed to? We'll be up and down the coast and then heading back east over the next few weeksĬlick to expand.Your setup plan looks good for your purposes so far. I've got some more details of my "simple" install in my build thread, just replace any reference to the ML-ACR with any generic 200-500A relay and ignition triggered switch. Shop high-quality RV parts and accessories. While the truck is parked at home it lives on a Victron 25A charger to keep both batteries topped off, but only because it'll sit there for several days at a time, and the fridge is in the truck and powered on 24/7. RV Parts Center offers a great selection of USA-made motorhomes parts and supplies at the best prices online. Unlike diode isolators, this system provides an engine driven alternator with the opportunity to begin charging the main battery before connecting the auxiliary battery. Select Year, 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015, 2014, 2013, 2012, 2011, 2010, 2009. Yes you can run a DC-DC charger to be "perfect", but that isn't a need, at least personally. Intellitec’s Battery Isolator Relay Delay/E offers a low cost, reliable approach to charging multiple batteries. An isolator is great if you get the adjustable output alt. My '21 charged around 13.9-14.1 usually, so I popped in the GM Diode and I'm generally in the 14.1-14.6v range now. not a great idea with the other battery going dead. I simply go off of what is printed on my Northstar's (14.4-14.8v).
Radio Install Dash Kit & Wires, Car Stereo Mount for GMC (271942724502). People have quoted Northstar as saying "anything a modern vehicle puts out" as well as "14.2-14.7v", other brands seem to be somewhat variable or vague in their answers. STINGER SGP35 500 Amp Current Relay Battery Isolator 12 Volts Application. FWIW, I have a Blue Sea ML-ACR on mine, which is capable of ~500A IIRC, and also includes the override switch and automates the connect/disconnect based on voltage from either side.įor charging voltage, it really depends on what source you talk to about what the actual charge voltage requirements of each AGM is. I would recommend going with a PAC200 or PAC500 (or similar) relay instead of the 80A units due to the alternator's output (and potential charging) being >80A at some points. There's no real reason it wouldn't work, and IIRC, Antman's SPDT switch was to allow the solenoid to be overridden to force the batteries to either stay connected, be ignition controlled, or disconnected from each other.
