Thank You

Getting ready to leave on a extended trip and wondering if anyone has filter number for 370 Yanmar oil filter, and Kohler 8kw oil filter and impeller kit. I have the others but cannot read the above numbers on oil filter till I remove them. I want to order numerous ones for the trip. Also and...

Don I agree with you.. Thank You Jerry

Seevee 1) 8D AGM, 3) 8D AGM house. and bow and stern Thruster AGMs. Range is LP, we use IPad for our TV with unlimited data, Still in Michigan won't leave till Oct. We will use NEBO as Kickback. This MS is a month old to us and I just trying to help with the voltage loss. Jerry

Seevee What I have found out is that the multi battery isolator has a drop of over .62 volts. I have a different one coming which has voltage drop of 0.02 to 0.1 volts. With that over half volt gain should put me in a good shape. We have a single Yanmar, no inverter, plan on anchoring out often...

Not wanting to reinvent the entire current charging system, I would just like something that would take the place of the model 1203 Pure Power Multi Battery Isolator.

Don Yes I did look over your charging system upgrades. I know that things constantly change , some times for the better lol. I was hoping that the group would respond with their ideas . The Battery Monitor looks like a must have addition. And Thank You for your Web Page lots of good...

Yes, and to research a different Multi Battery Isolator.. Pure Power 1203 Is losing at least a half a volt . Would like to find something better that is recommended

Follow up Post... We I confirmed that solenoid was for the Air heater. What caught my eye was the voltage change with it click.... After a couple more hours... It dawned on me that I had been turning engine on and starting from lower helm... So to try and figure this out I went to the upper helm...

Thinking about this solenoid I’m thinking it is for the air heaters that are on Starboard side of engine???

Another pic with terminals exposed

Solenoid above dip stick

Going to try to load a pic of solenoid from ipad

Been checking with test leads and the what I will call the EXCITE wire had no voltage with ign off.. with ign on the exite wire ( vertical wire on alt) had 1.4 volts the L wire or horizontal wire had 12.28…. There is a solenoid on the port side of the 370 yanmar that has two good size wires...

Everyone : read Post 29 again.. At one point I had charge then no charge… ??

Don, Going back down today and check and test again,, going to take notes today.

Don I looked under dash at lower helm and did not see a sea fire module. Maybe its under the upper helm dash I will have to look there tomorrow, but I did not see it at lower helm. I thought earlier that it would have been less wire distance to lower helm so that is where I looked... With...

First The battery wire on Alternator comes from the A post on the Battery Isolator, not from Starter I verified Ground was good, and had just 12 volts when key or toggle was on, also still had low 12 volt when engine was running... Wanting relay what I have at Alternator

Naybe this time I got photos

Some photos of what is installed to charge house bank, engine battery, and both 24v thrusters

I did confirm that I had power on both the terminal on the T shaped wire plugged into back of Alternator Where do I look to find the Sea Fire box ?? Do not know how to Post Pictures to this site. Bacchus or Done said he posted a link on how to post pictures but it did not appear...At a Total...

More information... From the Battery terminal on Alternator the cable runs to a Sure Power Multi Battery Isolator, Model 1203 . I removed the cable battery cable from alternator to Isolator and removed one of the battery lugs off Isolator and bolted the two together Started engine and no charge...

Well New alternator , and still not charging.. At one point I remember reading about the way the sea fire was wired on Mainships... i was looking at the SeaFire unit at the helm station,, and noticed there is a switch to toggle from over ride to Normal.. I it was on over ride.. I switched it to...
