Thread: relays in engine fuse box

I have always been told that landrover ones (siemens brand) are rated at 30 amp. I dont see any problem with using any other brand aslong as the rating is the same. (It Might pay to email the previous owner to see if he took it out for a reason though)

It might be useful.........if it was fitted.

Australian spec cars didn't have secondary air injection.

Sounds like a good spot for a spare relay though .

Hi Paul,
Yes LR relays on the P38 ARE vehicle/color/engine specific & a standard relay will not fit. The pins are different & can/have caused damage to the BECM..Not good. BECM's arent cheap.
So please be careful.

Thanks Scouse.

There you go - I learn something new every day

Now to get some spare relays - a few of mine have burn marks that don't look very healthy. Maybe a new fuse box for good measure too.

Hi Paul,
A spare fuse box is a good thing. With the amount of heat build up under the bonnet the fuse boxes tend to crack the circuit board in them, which can lead to all sorts of malfunctions & lights displaying on the dash.
If u can see signs of burn marks on the relay tops..I would definately change the fuse box also. Bit of preventative maintenance & also makes the vehicle more reliable.
Cheers

paul,

their are lots of relays that are compatable with the range rover at any auto store just check the circuit driagram. but i use yellow- bosh 0332 019 457 green- bosh 0332 209 150. I change the whole lot and kept the origonal ones as spares, not failed yet 2 years ago.

For info:

I recently (6 weeks ago) imported a genuine P38a MY2000 fuse box from Brit Parts. It and came loaded with all fuses plus spares but no relays.

I also ordered a stack of yellow and green relays. The relays were a touch under A$10 each and the fuse box was A$194. DHL delivered the lot to the door from the UK within 5 working days of placing the order for about $30.

The original fuse box was 9 yrs old and was stuffed... cracked and burned around Relay #7 position. Several (yellow) relays had dark brown telltale burn marks.

dismantled the old box (couldn't help myself )
It is a complex " two storey" PCB with a flexible conductor running the length of one side joining both boards. Additional "direct" connections are evident between the solder sides which are internally facing a few mm apart. They are jam packed with push fit connectors for fuses and relays which as expected are themselves interconnected... I put it in the bin
