I recently had an alarm going off on my 2002 262 with Volvo Penta DP and had a heck of a time trying to determine what the cause was. Oil pressure good, temp good, charging, etc. Turned out o be a disconnected wire to the flame arrestor. Is there a list of error codes that is available? That would have been most helpful Also, is there an aftermarket code reader that is available to owners? Or equally good, is there a shop manual available? I had always had Mercruisers before and manuals were always easy to obtain.
