    Mercury 6.2 ECT DTS Axius Voltage Issue

    I feel more suppressed than the relays . . . or would that be depressed, not suppressed. Anyway . . . based on the diagram of the relay, I am thinking it does not have a diode. I've looked online for specs, and it mentions "diode & resistor versions available". Although the relay is a...

    Mercury 6.2 ECT DTS Axius Voltage Issue

    Thanks for everyone's help on this . . . The inputs help from getting tunnel vision, which is easy to do on things like this. I have the outdrives waiting their turn for TLC. The gear oil is black as coal and the port drive has a delayed shift. Probably will do the poor man's clutch fix on...

    Mercury 6.2 ECT DTS Axius Voltage Issue

    OK - I'll get my contortionist outfit on and take a look I believe it is all stock set-up, but I'll check. All of the wiring is jacketed in the black conduit stuff or wrapped into a harness right up to the connectors. . . tough to see the actual wires.

    Mercury 6.2 ECT DTS Axius Voltage Issue

    FWIW - Here is a diagram of where stuff is on the engine. Most of the stuff is tucked under compartments in the plastic cover, so it is a bit tricky to reach. I usually have to un-button everything I am getting battery voltage at the back of the engine, but I'm thinking I should check the...

    Mercury 6.2 ECT DTS Axius Voltage Issue

    @Fun Times I am not sure of the wire color on the back of the alternator, but the protective boot is orange. (sorry for the delay in response)

    Mercury 6.2 ECT DTS Axius Voltage Issue

    Another thing that I just thought of is that there are quite a few circuit breakers up at the helm under the instrument cluster. I should check those to see if there is anything of significance.

    Mercury 6.2 ECT DTS Axius Voltage Issue

    No I cleaned the starboard side. I did quite a few things in short order, so it is hard to say what may be contributing to it. Battery upgrade New Alternator Cleaning Electrical box

    Mercury 6.2 ECT DTS Axius Voltage Issue

    Here is the area of the wiring diagram for the MPR. . The power feeds end up over on the other side of the diagram at the connectors to the PCM. . Based on the PCM Manaual, I beleive that power is on connector A (58) pin A2 and Connector 3 (56) Pin A4. Here is the detail from the PCM 112...

    Mercury 6.2 ECT DTS Axius Voltage Issue

    My boat has 340 hours. Starter batteries (2) are new. The Starboard alternator stopped charging properly when I test ran the engines this year. It was replaced a few days ago as per my write-up. Each engine has its own battery & switch. It is a Mercruiser 'faux pas' to run the engines on...

    Mercury 6.2 ECT DTS Axius Voltage Issue

    #1 - Yes, voltage warning on the starboard engine . . . sort of got it fixed after a while. #2 All over the place. Everything VesselView and Diacom are coming from the PCM. I have taken other readings with my DVM. The voltages are there, it is just that the PCM isn't seeing some of them...

    Mercury 6.2 ECT DTS Axius Voltage Issue

    BTW - I pulled and re-connected all of the connectors on the PCM 112, the Smartcraft junction box at the helm, and another PCM looking thingy at the helm. No difference.

    Mercury 6.2 ECT DTS Axius Voltage Issue

    Thanks, AD . . . There were a bunch of wires connected to the starboard isolation post . . . one of them was a bit 'sparky' when I re-connected it after cleaning the connections. I'll get the DVM and start poking around, both with ignition off and on. I'm coming in close behind you on not...

    Mercury 6.2 ECT DTS Axius Voltage Issue

    . . . the hits just keep on coming . . . I've been doing a bunch of work on my boat and engines . . . mostly of the electrical nature. Anyway, I am getting low voltage warnings on the starboard engine. Once the engine starts the warning goes away and the VesselVeiw says "OK". I then noticed...

    Bravo 3 seacore - U joint replacement?

    IIRC - there are standard u-joints and heavy duty versions. The difference being the bearing spindle. If you get the Mercury branded ones, it will be top-dollar. If you can find the correct aftermarket type, it will be about half the $$. All the new bearings are non-grease-able type . . ...

    Bravo 3 seacore - U joint replacement?

    You'll need a large 'C' clamp to press the bearings out (after you remove the retaining clips). . . . (there is a tool to that too!) I got my outdrives off right now for some repair & maintenance. . . Here is my thread about fixing a previous set of Bravo 3's . . . Page 3 has a little bit on...

    LiFePO Batteries ???

    On another note . . . I was able to clean up that starboard electrical box using some harsh chemicals . . . . . The floor is pretty well cleaned up, but I need to figure out something to clean up the walls. I was able to clean up the starboard isolation post and put it all back together. ...

    LiFePO Batteries ???

    Charging of the LFP batteries does not go through the AgroFET. The LFP batteries are connected directly to the Orion. The ArgoFET is on the lead-acid side. The best that I'm seeing out of the solar panel is 62 watts . . . mid-day full sun . . . So, that yields about 4.5 amps of charging to...

    The new alternator works . . . it even likes the DC-DC charger. :D

    Mercury 6.2L ECT Seacore Alternator Replacement . . .

    Quick Update . . . OMG . . . it's working !!! :oops: I ran the starboard engine for a while . . . normal voltages at idle and fast idle. It even likes the DC-DC charger. (y) On to fixing the outdrives . . . :rolleyes:
