Please help... EP-20 / LMF-400... Help.

[DippinPete]

Lost all engine data on my port motor. The device bus still shows, but I am unable to unconfig it. When I go to uncofig, it cycles, but when it returns to the bus device screen it still shows a "Port" instead of as "Unconfigered"... (When I unconfig the starboard one, it does what it should (same for both fuel interfaces)...

I disconnected all power, did resets, etc. Even disconnected all plugs and reconnected. Same problem.

It was literally working and then it stopped.

Motor appears to be working just fine -- just no data coming over the NMEA.

My guess is that I need a new EP-20. My set up is a little old (2006 DF250)... my Firmware for the gauges is 1.0.

What are my options?

Thanks,
Pete

Replied to your post on THT.

It is likely to be either a failed physical connector (a bad T piece or a broken wire in a plug) between the engine and the network, or a failed interface cable.

I suspect you have to old Lowrance blue T pieces? If so, they can get corroded, so disconnect the interface T piece and check all sides of the plugs for corrosion. Try swapping T connectors between the interfaces to see if that helps to reveal one that has failed internally. Check the plugs from the interface cable/adapter cables to the SDS plug on the engine for corrosion or breaks.

If your checks as suggested above reveal no obvious bad connections, then it is likely to be a interface cable gone bad (BTW no-one refers to them as a EP-20 any more, they are not sold under such a label, just referred to as the Suzuki engine interface cable for at least last 5 years.)

If you need a new cable I suggest you contact Mike at International Marine, you will need a new cable that is programmed with software version 2.30 to suit your 2006 year engine. The new cables come preprogrammed with either V 2.9.0 or 3.5.0 and neither of those will work with your engine, but Mike seems to be one of the few dealers able to source cables than can be programmed with V 2.30.

Thanks for the reply!

I've checked and triple checked all the connections. I've done every power reset I could think of.

The *only* thing I can think of is that I have NOT run the motor with the engine interface disconnected. I also haven't tried taking the white power (ECM power) wire off the battery AFTER I took the engine module off. And then put the Engine module back on... not sure if that would help at all, but it's about the only voodoo I haven't tried.

I have sent a PM to Mike at International Marine (yesterday) and plan to call this morning. I really appreciate the tip on the versions.

I'll hunt this thing down!!!

Many thanks for your help!!

Oh! And THANK YOU about the tip on the name change!!! Duh. (Can you tell I'm new to Suzuki? LOL)
