Corsa B 1.7 Diesel Glow Plug Relay

[Seafarer1966]

Where is the glow plug relay on a 2000 plate Corsa B 1.7 (Isuzu engine) diesel?

i don't know the answer to that SEAFARER,
But if nobody comes on to tell you,
Get some one to turn the ignition on whilst you listen carefully under the bonnet, you may well hear it click as it switches off.

Hi, look in your Handbook Seafarer under fuses Etc.

Thanks Logic but my problem is that the glow plug relay isn't switching off. The glow plugs stay on permanently. I tested the plugs with test light and yup those blighters on are on all the time. The glow plug light on the dashboard runs on a separate circuit to the plugs themselves so even though the dash light goes off after a few seconds the plugs stay on.

TWR thankyou for your tip. If I had a handbook with that snippet of information in it do you really think I'd ask the question on here.

Wish I could help you - I've got the same problem with my Jeep Cherokee (Renault 2.0 L diesel engine). Trying to figure out why the battery isn't charging properly (the alternator seems OK) and goes flat if I leave the ignition on too long without the motor running. I then discovered that the 2 glow-plug relays are getting very hot even though the pre-heating light on the dashboard is off. I concluded the relays aren't switching off, therefore also the plugs,and thus draining the battery, but why? What controls the relays?
Can anybody give me a pointer please?

i had the same problem, on combo, corsa van...glow plugs stayed of for 5, 6 mins, until the (engine is hot now sensor) turned them off. This over rides normal glowplug timer as you dont need glow with hot engine. After much trouble and trying a new timer unit i found the fault was the altenator.....believe it or not if the alternator warning lite lead is disconected, or the altenator goes on the blink the glowplugs stay on...odd fact
