Why does the black and red wire go to common on perko, and cant understand wht his said about the red common wire.

Merci beaucoup ❤❤❤❤❤❤❤❤❤❤

What if it’s coming from the vent line? I’ve checked both main and vent line and still does this.

the problem is the fuel air vent. If the fuel air vent is clear then there will be no "well back or spit back". if the fuel air vent is clogged or closed then there's not enough air pressure to push fuel into the motor, it will stall on idle or while cruising. Fuel air vent prevents the tank from a vacuum state, not an absolute vacuum state but enough to prevent fuel into the motor.

Can you do another video with the isolator dual battery setup.

glad i saw this, now i know what to remove on my Majek. checked the vent and all was good. it seems my flap is not working as it should and not allowing me to fast fill the boat.

let the engineer speak dammit

Dal video non si capisce come funzioni...

Sounds like it might cause other issues

What about charging?

Can you pls help me i have to install Buth with two engine

I know this is an old video I wish you would have zoomed in a little bit on that 8501 switch where it says 350 cranking amps momentarily 250 constant and you hook it up to a 750 cold cranking amp battery what's wrong with this picture great switch for solar panels and inverters I wouldn't want to look at any engine

Looks like it backed up because he blocked the vent. Then if the valves shuts don’t you still spill the gas you’re pouring?

Can you turn on your motor with the cranking battery in position 1 on the selector switch, then turn the switch to "ALL" to charge both cranking and house batteries after you have started the main engine?

I thought John wanted the Perko expert to show how to do this. John never let him speak.

Excellent video. In my boat I have 2 engines, 4 batteries and 2 Perko switches connected the same way you show on the video. Do I have to run a wire in between of the common points of the two switches?

Hi

How br made in ...?

Why do i need a common ground post. Can I just connect both negative battery posts together, and all negative wires to either of the negative battery posts? I don't have room for a separate common ground post.

common pole of the switch bond with common ground (both negative lead of battery) can blow up. Is the wiring working?

thanks! REALLY HELPFUL VIDEO. -----The tank has to be able to "breathe". I think mine is clogged at the vent to the side of the boat

GREAT VIDEO... thank you!! I have only one question, if I may. In my distribution panel, on the fuse box side, I have both positive AND negative posts for my battery, along with pos and neg posts for the converter, that will recharge that battery. Since you instruct to run the common positive (3) lead back to the distribution panel.... SHOULD I also run a negative lead, from the distribution panel (fuse side) to the negative common post demonstrated above?

What gauge wire are you using?

...thanks to the point ......... not to much waffle like other videos I have trawled through......

the guy with the beard is just too smart for me....

Thank you for that very nice and easy

I have this one on my hot rod. Will this eventually drain my battery if it's left on?

😎👍

is a common ground necessary or can it just be the battery negative.

BEST VIDEO, most simple to understand. and more importantly, showing us visually where the wires need to connect.

Awesome video, thank you! How connect dual bank charger on this installation? Thank you.

Has anyone added one of these? The diameter looks too small for my fill hose which I believe is 1.75"
