EIM Issue? 2005 280 DA

[Anglers Rest]

I've lost all functions that run through the aft EIM; blower, windless, cockpit lights, anchor light, bilge light. Everything started flaking out and then went out all at the same time. All wiring appears to be tight to the EIM and all breakers are on. Is there anything else to check or is pulling it out the next step?

The Sea Ray mechanic says we'll probably need to replace the system. There are replacement EIMs however the new ones don't talk to the old switch pads. Since the blower is on the left switch pad and the other functions are on the right switch pad, it means replacing both switch pads and both EIMs. Ouch! $2,700.

Anyone have a similar experience or issues after the upgrade?

The only very limited thought that comes to mind is check and double check grounds. I am not being sarcastic. I went through a similar experience. I ran a spare wire from the battery and carefully made contact. My lights came on. Now it was just an issue of chasing down the bad ground. I found it on a loose bolt with a corroded ground line and bad crimp on.

Make sure you have +12VDC and ground at the switch pads and on the EIM.

+1 start by verifying power AND GROUND at the EIM If necessary run a temp ground from the stud to the battery or engine block.
Same with 12v power, run a temp from the + battery to the EIM
Current make things work ,not voltage so make sure all the grounds are good. With a poor ground you might read 12v but no current can get past the poor connection.
Its like trying to start your 8.1 with a transistor radio battery , the voltage is there but no current

$2700 would buy a lot of nice switches, wire ,and circuit breakers. Nothing like a real on-off switch for boats.

Voltage checks out good; 13.15 volts. Ground connections on both ends are tight and corrosion free. This is a fresh water boat and no signs of corrosion anywhere. I'll try running a new ground to the battery tomorrow. Thanks for the suggestions.

Hope you get this sorted. I have a very similar issue, if I run a new ground to a different ground point my dead circuits come live. Can any one advise if a permanent feed to this ground would be safe and leave the existing ground as it is ? Also what dose EIM stand for ?

Yes, you can run the new ground and leave the old one in place. EIM = Electronic Interface Module
