IBS-DBS w/ RBM Installation
In preparation for the IBS installation I had a new OEM alternator, starter, fusible links and alternator cable, along with Fourrunner's Heavy duty cable set which includes: Battery to starter cable, Negative to block (with 90 degree lug) cable, Negative to chassis cable, Ground strap from head to firewall, and Ground strap from battery to fender installed. I also installed Slee's 2nd battery tray and washer bottle relocation kit. The IBS kit was purchased from Sierra Expeditions over a year ago during one of the group buys, I've just been waiting to find the time to do this installation.
The installation was fairly straight forward with no requirements of an electrical engineering degree required. I did run into one big minor hiccup though... with all the terminal end crimping and heat shrinking I overlooked one connector... I missed crimping it and just heat shrank the cable and terminal end together. It was the positive cable to main battery from the battery monitor wiring harness. This gave me a constant low voltage on main battery indication. I spent the next day trouble shooting every component of the system and even checked that positive connector a couple of times. George from Extreme Outback is the US distributor for IBS and provided a level of customer service that was well above going above and beyond. Narrowed it down to the Battery Monitor and sent it to George so he could perform all the system tests and try and find a problem. Couple of days later... no problems found everything worked as advertised. We concluded that it could be nothing other than the red cable on the Battery Monitor harness going to main positive. I decided to just cut the terminal end and open it up. Once the heat shrink was off noticed that there was no crimp on the connector... problem solved.
IBS-DBS Dual Battery System with Microprocessor allows visual indication of main and auxiliary battery charge with power on and off, allows visual indication of charge voltage, allows automatic charging of both batteries, allows manual battery linking during high power consumption requirements such as winching which reduces the load on the alternator, the wiring and the batteries. Audible and visual alarms are also present during low battery or link failures.
IBS
Relay Boost Module allows link starting with auxiliary battery if main battery is completely discharged (dead).
IBS Test procedure This should be included with the installation kit.
Main battery.
Auxiliary battery grounded to fender well and to main battery.
Positive, Negative, and battery monitor wires ran under forward top cross member.
IBS 200 amp relay and RBM mounted just behind 2nd battery tray.
Battery Monitor installed on IBS swivel mount. That wire mess will be cleaned up with the installation of a couple USB charger sockets.
I'm very happy with the outcome of this installation and the IBS DBS ease of use. Another big Thanks to George for all his help. I didn't have the tools to cut or crimp the big wire, so West Marine is the place to go if you need to use some big wire tools. The directions for the IBS-DBS RBM installation supersedes the IBS-DBS instructions also it's recommended to run a ground from main to aux. along with having both batteries grounded at the fender wells. It's also nice to know that I have a back up for the main battery while out on the trail and a solid foundation for future electrical needs. Next up a Blue Sea 100 amp circuit breaker and 12 circuit fuse block don't know where there going to be located yet though.
