1998 Voyager

I own a 1998 Voyager UK spec, recently when driving it judders and the
revs drop for a second and then continues ok, the battery light
sometimes comes on when this happens, my husband has checked the
alternator etc and the battery is ok, anyone out there with any similar
probs! or info?

When you say the battery is OK, how did he check that? Is it old? Batteries
can develop occasional internal shorts as they get older and plates loosen
or they accumulate crud. Sometimes even new ones can do that. This won't
normally show up on a test. The only way to be sure is buy or borrow another
battery and see if the problem goes away.

Hope this helps.

 

I'll bet it's the ASD relay (Auto Shut Down) , when the contacts get
old, they corrode and don't pass full voltage to the ignition coil and
the fuel pump circuit. It's intermittent and maddening. You can check
by putting a voltmeter on the positive terminal of the coil and see if
it gets full battery voltage while running. Other symptoms are a fuel
pump that changes pitch intermittently, making you think the pump is
bad, but is really fluctuating voltage. This happened on my '91.
Cheap to fix, though.
