First the details.
TIU is rev L, both remote and TIU updated to 5.0 Engines in question GP-7 20-20363-1 from 2014 and RS11 20-20213-1 from 2013. Both PS3 engines
Some history on the RS11. About a year after purchase there was a flash with burnt smell coming from the engine. I removed the shell and found a pinched wire, there were some burned up trace and wires which I was able to fix and after that the engine ran fine with all functions working.
Now I create the lashup, doesn't matter which is in the lead or the back engine, forward or reverse. These are the issues I'm having and been having since I purchased the GP7.
Issues:
1. Sounds from both engines do not stay in sync , Volume pots both full on. Turn down the volume via the remote the RS11 will go to zero way before the GP7. Turn up the volume the GP7 will get to full before the RS11
2. After a little bit the RS11 will stop responding from idle. Either direction the GP7 will be spinning it's wheels and the RS11 will just site there.
3. This one I just noticed, the marker lights stay on but on the GP7 the number board lights go out when the other engine is in the lead. If reversed and the GP7 headlight comes on the number boards also come on.
I've done feature resets, engine resets, removed from the remote, re-added and the same issues keep popping up
My thinking is even though the RS11 works just fine independently, the electronics still must of taken a hit and either the firmware needs to be reloaded or I need a new PS3 board entirely.
Thoughts in the manner? Clearly the RS11 has something wrong, and I'm not seeing when it's running alone but in a lashup it behaves badly.
