AR210 Battery

[Lyons7]

Anyone know proper way to connect this battery? Yes I’m a noob but haven’t seen 5 wires for one battery before. 1 positive, 2 negative and 2 ground wires. Picture attached, any help is appreciated.

Red to positive. Negative to negative. Ground to negative. Double check your "grounds" though. I'd hate to give you incorrect advice.

Would both “grounds” go to negative? So both black (negatives) and both grounds all together on negative?

 

[anmut]

Grounds are usually negative.

Grounds are negative. Red is positive. However, Yamaha is known to make one of the positive wires black. Don't ask why. Wait until you hear from someone with a '19 to confirm that all of these black ones are ground/negative before hooking them up (people have traced them and found the right one to go where). Hooking up the wrong way can fry your ECU and other stuff....

An example... https://jetboaters.net/threads/help...aha-ar230-wiring-at-battery.13433/post-233887 Different year from yours, tho.

There should be 1 thick ground wire for each engine. 1 thick positive wire to the battery switch and then 1 or 2 grounds for miscellaneous equipment. All grounds go to the negative post.

On my 195, the bilge pump positive was wired to the hot terminal of the battery switch instead of the positive post of the battery.

Is this for a 210 or a 19footer? Did the dealer not connect the battery? Is the boat wired for house and start battery or just a start battery?

This is a 210 (2019), just a start battery. I had the dealer winterize it and they disconnected it before the winter. Haven't been able to find a picture and the manual wasn't very clear. Just wanted to make sure.

Red to red, everything black goes to black..I have basically the same set up.
