Here is the fuse location chart for the U300. Taking a test drive with a 5 amp fuse installed sound like a good way to sell a new ECU. I've worked for dealers as a kid, a big reason I never take a vehicle into a shop. Sure looks as if it calls for a 10 amp to me, especially since there is a 10 amp installed. They agree 100%

So, we have the same 6V-92TA Detroit with the same DDEC II ECU. Does the coach in question have the same location placard with the same fuse rating? If so, why was a 5 amp fuse installed for a test drive. I may not be Perry Mason but...

Our fuse panels are the same it has a 10 amp for the ddec. I believe the 5 amp fuse in question is lead 439 in ddec wiring which by chart says ignition.

Ken,

I see the fuse in the schematic on reply #20. Looks like it goes to the ignition as you said and has to do with the low coolant level module and the cruise control. I take it that the low coolant module is in the ECM itself? Is it located in the fuse location map in reply #25?

Looks like I may have to eat some crow pie as far as S&S goes. :D

Here is the complete DDEC II troubleshooting manual in PDF format: https://ia803107.us.archive.org/4/items/detroitdieselddeciidiagnostictroubleshootingguide6se4891986ocr442pages/Detroit%20Diesel%20-%20DDEC%20II%20Diagnostic%20Troubleshooting%20Guide%20-%206SE489%20-%201986%20-%20OCR%20-%20442%20pages.pdf

This PDF might be good to download for 6V-92TA owners.
