just a quick one,was wondering what a delta batt error would be,what does it mean

This error is caused/flagged by the +12V supply to the ECU dropping out for a short period of time. Something like turning the ignition switch off and on very very quickly.

Could also be a bad earth

...or a blown alternator diode.

All of the above 100% right Low voltage,also ive experienced something weird.Got a friend to buy a new bosch relay for me on his way to my house.Put it in as the ecu relay.Did not notice he got a reverse relay wich is on with the ignition off and vice versa.Some reason ecu turns on with ignition on anyway so i didnt think anything was wrong.2 days later my battery voltage started to drop alot to the stage it would kick over anymore.Thought it was a wiring problem or all of the above options.After doing my head in for a couple of days thinking,Recharged the battery started car was checking wiring and touched the relay it was that hot like it was about to melt.Changed it not a problem ever since.
Got these errors at variuos times

delta bat
injector peak
and the scariest 1
