I decided to install the BEP 716 on my Whaler and finished the upgrade today. I choose the BEP 716 over the Blue Sea
5511E Dual Circuit Battery Switch and the 7610 Automatic Charging Relay because I have a good performance history of the 716 and have some space limitations on the aft bulkhead under my helm station.

The installion is connected to two Cabelas Group 24 AGM batteries (1175 cranking amps) which are serviced by a Guest 2620A battery charger. I like to keep my batteries in top working order. I'll keep you posted as to the on water performance. Here is a picture of the installion.

Tom--That is a very neat installation. Great work.

Thanks Jim ..... here's one more picture. 12005041/file.jpg

Tom--You boat's electrical system looks absolutely top-class. I know you do a lot of fishing offshore in the ocean. That is no place for anything but the best of gear. You set up is a model to be followed.

Thanks very much Jim.... guess I'm AR when it comes to electrical safety (my Navy training kicks in). It's really been amazing some of the electrical system nightmares I've seen on prospective clients boats.

Before I agree to any installion job I always conduct a sight survey to find out what I'm facing good or otherwise. If what I see is good I'll point that out and conversely if what I see is substandard I point that out too. I always tell my clients that a good electrical system is the cornerstone for a solid performing boat and electronics package.

First I must say very good looking job there!

I am setting up my project outrage with new wiring and am using the BEP vsr with the dual bat mini selector switch (1,2,both&off)and if you don't mind I have a few questions?

1. The main fuse block that attaches to your distribution panel-what size is it?
2. Where/ how is your charger wired in?
3. It looks as if you are using the negative terminal bus on your blue seas distribution panel and if so do you have another groung bus somewhere or is that sufficient?
4. Do you think I need one of those main curcuit/reset swithes found on later models?

Very clean installation, nice work. I've been using the same BEP unit for about a year now, with great results. It makes battery managment simple and effortless, and should result in longer battery life. I can tell you that both of my batteries state of charge has improved significantly since making this upgrade, with dramatic improvement in the house battery.

You certainly set the bar high for the rest of us!! I also have a couple of questions:

1. Do you think that the separate fuse on the feed for the Blue Seas fuse block is necessary? With such a short run I would be tempted to just make the connection directly with a wire sized to carry the full load of the fuse block.

2. I see you leave the in-line fuses in place for the accessories that are powered from the Blue Seas fuse block. I cut mine off and depend upon the fuse block for protection to avoid redundancy. Is that a mistake?

3. There is a very fine black wire from the Voltage Sensitive Relay module. I have never used this type of relay but I assume this is a ground wire for the voltage sense circuit?

George & Dave .....

Thanks for the compliments gents. I'll answer George's questions first:

1. The Blue Sea (BS) mini fuse block is rated for 30 - 80 amp fusing. I use a 40 amp fuse which is 66% of the charging capacity of my OPTI 225's alternator.

I usually use a BS Thermal Circuit Breaker Series 187 rated 25 - 150 amps (I install the Series 187 model # 7138 rated at 40 amps) but for my installation I didn't have one in hand so I used a BS mini fuse block. Here's what a BS 187 series looks like. 12095076/file.jpg

2. There is one other neat trick you can do with the BEP 716 and that is you can connect a battery charger to it by connecting the positive output terminal of the battery charger to Stud "A" on the starter battery switch. You set the starter battery switch to "ON" and set the house battery switch to "OFF". This will allow the VSR to engage and charge both batteries. If you choose to use this configuration you connect the grounding terminal of the battery charger to the negative post on the start battery to complete the circuit. Here's a photo of the back of the BEP 716. 11514713/file.jpg

3. The BS Fuse Buss is connected to my Whaler's grounding bar. 12095709/file.jpg

4. I would recommend the use of a circuit breaker found on the later Whalers.

OK Dave ..... your up.

1. If I understand your first question, I prefer to use a thermal circuit breaker or mini fuse block rated at 66% of the outboards rated alternator capacity in between the 716 and the BS fuse buss, just in remote chance I get a spike.

2. Your assumption is right on the money in regards to the redundant fusing. My next part of the project is to take those useless glass fuses out between my electronics and the BS fuse buss.

3. You are correct .... the small blck wire that is connected to the VSR is a ground. This is the wire in question. 12095938/file.jpg

Hope this answers all your questions?

Thanks again!

What is your opinion of using the 185 series in leiu of the 187 series? both being 40 amps.

George .......

Either one you choose your a winner.

Just finished rewiring all my electronics and added a the larger Blue Sea Fuse Buss. I'm in the process of repowering my Ventura. I've sold my Opti and will repower with a Suzuki 250. This will add a net weight gain of 72 lbs on the transom. My 210 Ventura is bow heavy to start with so the added transom weight is not an issue. I will take some pictures of the repower.

You can see from the picture how the Ventura sits in the water. 12188351/file.jpg
