Hi All;
I went out this morning to start up the bus (87 Westy w/Gen. 5 I4 Golf engine;  FAS install), and my oxy and battery light stayed on after start up.  I shut it off immediately, went back to check.  Belt fine, wires connected.  I just put in a new ECU, throttle body (electronic/drive by wire), and MAF.  Cleaned and greased all connections in engine bay and under rear seat while troubleshooting ECU.  Alternator maybe?  If so, easiest way to check?  Any ideas or input out there?
