Sorry for the delay, my main news server is down...
Sorry but I'm not sure where the CB is on the C5 but what I would like
to point out is that you shouldn't be measuring volts but current
(amps) - and you need to know how to use a amp-meter - it's not the
voltage that is lacking but the if the amps are available (at the glow
plug terminals) and if so, are they being used correctly or fully.
