Q4, looks to be a standard setup and other than the VSR, I think it looks fine.
#BOAT DUAL BATTERY ISOLATOR WIRING DIAGRAM PLUS#
I actually, take the lid off my outboard and connect my charger to the the plus and neg terminals, and then this will charge which ever battery the switch is set to. Yes, you can charge your batteries on the boat.

You can use this to start your motor too, but maybe consider taking a small portable jump starter as well. If you want to replace your deep cycle, then I would stick with a deep cycle. That connects the batteries together and it will chage the second battery (deep cycle) when the starter battery is full, which means you've never need to change your switch from 2. As mentioned above, consider getting a VSR. How do I manage this system on the water so that battery health/capacity is efficiently maintained for a day out of stop/start cruising with the family or a longer run out to in-shore coastal fishing spot?įrom how you've got it wired, you would set the battery switch to two when you start the engine and then when running you might change the switch to both to charge them both and then when you stop the engine, turn the switch back to 2 Does the dual battery wiring setup (main cable connections between batteries, isolator switch and motor) reflect a standard setup that reflects good practice for such a system? (I need some confidence that everything is as it should be!)ĥ. Can I use my Ctek charger to recharge the batteries in situ (wired up in the boat) either one at a time or both at the same time with the existing wiring setup? What is best practice?Ĥ. Whatever type of replacement battery I choose I'm thinking to replace the deep cycle with a dual purpose (cranking and semi cycling battery) which might offer better redundancy on the water if my cranking battery unexpectantly dies. Can I replace the deep cycle battery with an AGM type battery and therefore mix battery types in the dual battery system, one wet flooded and one AGM? (My research seems to suggest that there are some advantages to AGM including no risk of acid spills, no maintenance beyond recharging, quicker recharging, and hold their charge longer during periods of no use)Ģ. I have now documented this as best I can in the wiring diagram I have attached to this post.ġ. So I bit the bullet and got down and dirty in the back of the boat to see how things were connected. I’m not techie minded and it was worrying me that I didn’t really understand how things were wired up in this system and how I should manage it on the water, particularly now that I wish to venture outside for some in-shore coastal fishing (not too far out). So the deep cycle battery (Century N70T 100Ah wet cell flooded) has now died and I will need to replace it. When a tried to recharge the deep cycle battery the charger reported an error at step 5, meaning that battery won’t keep a charge and therefore needs replacing. In most cases, it’s a simple as running a new large enough wire (meet’s ampacity and voltage drop requirements) and removing the jumper between starter solenoid and alternator on the engine.I have purchased a Ctek 5amp smart charger which I have recently used to recharge the cranking battery out of the boat (all 8 step process okay).
Here is some general advice, when installing a battery isolator, you need to make sure that your Alternator positive is only connected to the battery isolator and NOT the starter solenoid as normal. We always use battery combiners with outboard engines.

Unfortunately, I cannot comment on how to modify an outboard engine for a battery isolator. Is it simply removing the jumper from alternator output positive post to the starter post? - Randy Answer: However, I just watched a video by PYS and in the comments PYS says "Wiring an argofet to an outboard would involve some rewiring of the outboard alternator circuit." Any chance you can you give me an idea of what is involved for making this work with my new outboard motor? I have decent knowledge of 12v wiring.
I thought this would be a straight forward process, by connecting the alternator OUTPUT to the Argo FET INPUT per the instructions. I recently purchased the Victron Energy Argo FET Battery Isolator, 100A for my boat that has a 2019 Yamaha 300hp outboard motor. Wiring Battery Isolator on Engine Question:
