It comes complete with terminals that are simply connected to two batteries. What will work just as well is a Yandina battery combiner. Unfortunately, the F90 does not offer this feature. Yamaha refers to their second battery isolator as a "multi charge monitoring system". It costs less than the Yamaha isolator lead and is a hell of a lot easier to install. One wire to the positive post of the start battery, one wire to the positive post of the house battery and one wire to the negative wire of either battery. I have used and can recommend the Yandina combiner. Stop the motor and the device disconnects the start battery from the other battery(s). When ever the engine is producing certain voltage the device will automatically parallel two or more batteries so that each will be charge while the motor is running. The isolator device for the most part has been replaced by a device known as an automatic charge relay (ACR), voltage sensitive relay (VSR) or combiner.
SMART BATTERY ISOLATOR WIRING INSTALL
Plus, you don't have to install and route another cable from the motor to the battery. The problem with the Yamaha isolator lead is that in a number of cases it can cost more than a different component which offers the same benefit. When starting with 12 ~ 14 volts it is not desireable to lose any voltage as this will slow down the current flow. The electronic device known as an isolator has an inherent deficiency insofar as it uses diodes which result in voltage drop. You will need to add at least one to the Yamaha isolator lead for an SX motor. Early Yamaha isolator leads do not have circuit protection (fuse or circuit breaker).
I thought you might have been talking about that lead. Yamaha uses the term isolator lead to get current to a second battery. The benefit is to guard against a weak or dead battery from draining the charge of a strong battery in a muti-branch configuration.I just wanted to make sure that I understood what you were wanting to do. However, we also recommend that you have the following tools for the job ahead:Īlso below will be the part numbers if you wish to order any extra split sleeve tubing, lugs and wire.A isolator is a electrical device that divides direct current (DC) into multiple branches and only allows current to flow in one direction in each branch. We did not want to add these to our kits because we know many of you may already own them. We stock a range of 12V wiring tools for the job. Professionals will always protect wires with corrugated split sleeve tubing to prevent damage from impact and heat. Many other wiring kits do not include corrugated split sleeve tubing for your wires. We have created a second kit for this option: AMS40055 Protect your wires! If you wish to mount your second battery in the boot/tub/trailer, the thickness of the wire will need to be increased. This wire gauge should be perfect for engine mounting of the battery.
In this kit there will be 5M of RED 6B&S (6AWG) and 1M of 6B&S Black (6AWG). BE CAUTIOUS of other sellers that supply cheaper and incorrect fuse types, this will potentially cause damage to the DCDC charger and batteries. We have included the Projecta recommended 150AMP ANS fuse to use with the wiring kit. This kit will be particularly suitable for Projecta DBC100, DBC150 and VSR100. Most likely, yes! This kit has been designed to universally fit most types of battery isolators, be sure to check your exact requirements of wire and fuse ratings before purchasing. This is beneficial because a weak or dead battery will drain the charge from a strong battery if both are connected directly together. The primary benefit of such an arrangement is the ability to simultaneously charge more than one battery from a single power source (e.g., an alternator) without connecting the battery terminals together in parallel.
