Ive been having a starting issue lately. Turns over but sometimes will not start. Then yesterday my trim motor quit on me. I've traced it to the PDP. Relays are all good/fuses all good. I even switched PDP's between engines and same problem happens with other engine so I'm pretty sure it's the PDP. Number on side of PDP is 586736. When I look online for my engine it says I should be using PDP 586754. So my questions are 1) should I be using 586736(which I cannot find anywhere online) or 586754 (500$) And 2)can I get my PDP rebuilt from an electrical shop? Dave

Re: Power Distribution Panel Questions

before I spent 500 bucks on a pdp I would invest in a 10 dollar voltmeter and trouble shoot the board. The board basically joins pins of the relays and fuses via a copper track to pins that are plugged in. The trouble could be corrosion on the pins of the fuses and relays or a relay that failed. The board is a pathway so it may be whats plugged in the board rather than the board. If the board is melted then that's a different problem but if its just temperamental then I would trouble shoot it down to what the problem really was.

Re: Power Distribution Panel Questions

The relays were working fine when the buttons were pressed to operate the trim/tilt. I even switched all 4 relays (only 2 of them operate the trim/tilt) and every fuse (location #7 is actually the fuse that relates to trim/tilt) with the other PDP and when the relays from the problem PDP were put into the good PDP all worked fine and vice versa(relays from good PDP put into the bad PDP and the bad PDP still had same issue. I'm not very good with electrical work but I figure as you said the solders or "copper" trails probably cracked or aren't making a complete circuit within the board. Looks like the board is glued together. Can I just separate it and run a solder gun over all the points and "rejoin" them? FYI I have about 1200 hrs on these bad boys so I'm not complaining much but $500????? That's crazy lol. I'm going to try everything in the book before I just replace this.

I was just informed that DFITechnologies repairs them. I'll give them a call tomorrow maybe they can give me a rough estimate. I'll update as soon as I know tomorrow.

Re: Power Distribution Panel Questions

Does anyone know why all the schematics I find have my PDP part number listed as 586754 but the 2 on my engines are 586736 ? I don't see it as an updated model anywhere.

Re: Power Distribution Panel Questions

The only # I can find too is 586754. The 586736 could be a casting #.

Yeah that's what I think also. I'm going to try to get it rebuilt thru DFI Technologies. I'll find out Monday how much they want. I'm very hesitant to buy a used one not knowing if it was flooded or salvaged from underwater.

Re: Power Distribution Panel Questions

Made contact with DFI this morning. $210 for rebuild (if possible to rebuild). Shipping it out today. I'll update when I get it back. Thanks for everyone's help.

Re: Power Distribution Panel Questions

One more question before I ship this out. Is it plausible that the starting problem that began a couple weeks ago can also be linked to the PDP? I squeeze fuel bulb and feel fuel entering system, Turn key, high pressure pump kicks on, I wait until pump finishes pressurizing, then turn key fully and engine turns over but has no intentions of starting, I can do this multiple times (sometmes 2 3,4,5) and then it starts and runs fine. I've done the maintenance myself for 7 years now and know about indexing plugs etc. I'm not asking for an entire troubleshooting procedure at this time but Im just wondering if maybe it could be an ignition circuit issue within the board (location 5 or 8 maybe). Fuses and relays were all checked and are not the issue. Thanks guys.

Re: Power Distribution Panel Questions

Just a little update. Sent the PDP to DFI. I hooked up the PDP from the other engine to the trouble engine and the starting issue was resolved. Engine startined immediately on turn of key when cold and after running for a bit. Started it over 20 times in an hour and worked perfectly every time so it appears the starting circuit is also being interrupted on the PDP that is bad. DFI was advised of this issue and I'm hoping they can correct the issues. I'll update soon.

Re: Power Distribution Panel Questions

PDP returned in 3 1/2 weeks (212$). I hooked it up to the starboard engine (which was not the engine with original problem) and everything worked great. Trim/tilt works and engine starts up turn of the key. So, just a reminder that originally I removed the pdp from the port engine because it was bad and replaced it with the starboard engines pdp to confirm that the pdp was in fact the issue with the trim/tilt and possibly hard starting and the port engine ran fine and trim tilt worked so I left that pdp on the port engine. I attempt to now start port engine and it will not start. Turns over like a champ but no intentions on starting again. Switched the
pdp's and the issue stays with the port engine not the pdp. Appears to be getting fuel, can hear the fuel thru the hose when bulb is squeezed and the high pressure pump comes on for 10 seconds. It sounds like No spark because it has absolutely no intentions of running (just continuously turns over as if spark plug wires are off). Can I switch emm's to see if the issue follows the emm?

Re: Power Distribution Panel Questions

Not to be a smart a** but I still love those old carbed mtrs. Good luck with the new problem. I feel for you. It's up to you but switching the emm's might not be a bad idea.

Re: Power Distribution Panel Questions

Yes you can swap out the emm's just for testing. But before you do that make sure you have batt volts on the purple wire at the PDP, if no volts at purple wire, jump volts to it.

Re: Power Distribution Panel Questions

Turned out to be the starter solenoid. Switched solenoids and the problem followed to the other engine immediately. 30$. Sometimes it sends the 20v or whatever it is to the EMM and sometimes it doesn't. Thanks for everyone's help.
