ARB Elecrical Issue

[Hybrid_From_Hell]

Hi All,

My ARB Compressor suddenly died, after much faffing about its the relay wihich

has thrown in the towel , but at least I've found the issue

But

The relay on there is a :

BOSCH 12V 30A P/N 0332014112 (and no I don't have a F spare )

But

3.5 / 3.9 Fuel and Main relays look very similar and I shoved one in gingerly

and it works (without any smoke or acrid smells ) BUT its a :

BOSCH 12V 30A P/N 0332014113

Pin Config on the back is the same (5 Pins) and each pin has

the same number etc, so how safe am I using it, and does anyone clever know WTF

the difference is between a BOSCH 12V 30A P/N 0332014112 vs a BOSCH 12V 30A P/N 0332014113 ??

If it works then there's probably naff all difference, the part# could include a diode across the coil, a mounting bracket on the body, or anything really.

As Fridge said Nige Part No 0332014113 With diode.

Part No 0332014113 Without diode- Now use 0332019151 which was discontinued 08/2005

Wots the diode do then in an ARB ? and why on earth would they fit one with one ?

vs a relay with no diode ?, wouldn't a diode relay be more for a delicate ECU type situ ?

Diode is reversed across the coil, when you switch the relay off it stops the thing acting like an ignition coil and sending a +ve pulse back up the wire as the field collapses. The diode shorts it out.

Don't mention the words "short out", "Nigel" and "electricity" in the same topic or Gawd knows what will happen
