Battery isolator question

[bear_69cuda]

Good day,

I just purchased a 2003 Key West 1720 with a 2003 Yamaha 115 TRLB only 121 hours on command link..

Does anyone know if this engine has the charging battery isolator option like my 2008 F150txr had?

How about a link to wiring diagrams, or service manuals?

TIA!

Hey rodbolt! sure missed you on iboats! happy to know you're well and doing fine brutha!

No the 115 did not have built in isolator.

Thanks for the quick response...

I think I'll use a (VSR) voltage sensitive relay to charge my *****ing motor battery. Do you know the charging amp output on my motor? Thanks again for the help!

Also... Is there a link to service manuals? Or can I purchase on boats.net?

Regards,

Bear

It has a 20 amp charging system.
