![]() Post by-pass both were good, until a very hot smell up the hill, then not working. On a side note: I also noticed just before the bypass, that the indicators weren't working, nor was the fuel gauge. So here are the questions: What is this thing called? And any idea where I can get another? We were only about three miles from home, so things looked good. So, after a few checks, the AA guy reckoned that it was ok to by-pass, and sure enough the winnie started straight away. ![]() You could use a solenoid, but then you would really want to buy two brand new batteries of the same size type and age so they were matched. An isolator is great if you get the adjustable output alt. When checked there was a massive drop in current across it. When using Rugged Ridge Dual Battery Trays use the following locations: CJ-(76-86), YJ-(87-95) Mount the Isolator to the battery hold down bar. not a great idea with the other battery going dead. No idea what it is called, and it seems to be absent from all of the wiring diagrams too! There was no power forward of this unit. So did some checking and narrowed it down to the switch over thing next to the battery. No power to the dashboard, no clunk from the starter. Got back to the D19 after shopping, turned the key: got nothing at all. The ultra-flexible cables have heavy-duty plugs, and they come with a nifty LED light to show the cables are hooked up correctly at both ends.So on the first run after the improved door, I ended up on the side of the road. This gives us a quick-connect plug-in point at the winch mount for jumpers in case someone else runs their battery down. So we installed Wrangler Power Products i-Light Battery Jumper cable system. charging relay, and includes zip tie slots for clean and secure mounting of. Having a set of jumper cables that can be plugged in quickly is a nice item to have on a pickup. The Rago Secondary Battery Box offers protection on all sides of your Group. The ports in the terminal are designed to lock stripped cable ends in place with Allen set screws. They offer several styles of battery terminals that are gold plated so they resist corrosion. If your shop doesn’t have battery cable crimping tools, consider battery terminal connectors like those used by upscale audio shops. It should work nicely on your Chevy or GMC as well. The switch keeps the battery protected from total discharge when running lights or other accessories for a period of time.ĭual batteries sets Project Bedrock up to handle any electrical need we might encounter in the field. This unit sounds an alarm when battery voltage drops below 12.1 volts and 60 seconds later it automatically disconnects the battery (we will use it with the auxiliary) from whatever accessories are attached to it. Either that, or directly to the battery or starter relay. and is usually mounted on the frame rail between the batteries and the Telma. So instead of the normal 'simplified' version of a 3g install, where you connect a short Yellow w/white wire directly to the output of the alternator, you need to run a longer version of it from the BAT 1 post on the isolator, back to the alternators I wire. ![]() Then use the black probe to check voltage on the cable terminal attached to the isolator terminal that the red probe is on - it should read 0 (they should be the same voltage). 2 Pack High Power 4 Pin Fuse Box Relay 13500114/8385 Compatible for GM. 12V 140 Amp Smart Dual Battery Isolator Voltage Sensitive Relay Kit (Fits: More than one vehicle) 129.19 Was: 151.99 13.00 shipping or Best Offer SPONSORED Battery Voltage Stabilizer Improves Alternator Battery Performance for GMC (Fits: More than one vehicle) 40. Should you need a “boost” at start, an optional “momentary switch” can be easily wired in to the Smart Isolator that connects both batteries for one minute once it’s activated. Set it to DC Volts in the 20 range, and put its red probe on the isolator terminal so it stays there while you work. ( the 'body builder' terminals are on the Sprinter (starter batt) side, not the house side) (above is 2007 photo) (following are 2015) -dick. Theres also a short bus bar on the 'house' side, suitable for cable attachment. When you start the truck, the charging system brings the cranking battery back to 13.2 volts (full charge), then the isolator closes, the red status light turns on and the alternator now recharges the auxiliary battery. The isolator is under the drivers (left) seat. Fender corner brace has to be removed to get battery in and out. This separation protects the starting battery while allowing the auxiliary battery to continue to power the auxiliary loads. When the isolator senses the batteries reach 12.7V it opens the solenoid relay to separate the two batteries and turns off the status light. The 200-amp isolator senses the voltage of both main and auxiliary batteries and connects/separates them according to their charge, always protecting the main “cranking” battery.įor example, you pull the truck in to a jobsite, turn the engine off and leave all the warning lights on.
