earth grounding points in engine bay

Just a quick one guys, im fitting a heatshot unit for my windscreen washers in the engine bay just beneath the heater matrix on the right hand side, my landy is a 110 td5 2004, wheres my nearest earth grounding fixing or can i connect it to any bolt attached to the body work?

any bolt pretty much.

Easy to check with a multimeter.

set it on continuity, put one end on a known Ground, (starter casing) and the other to the bolt in question if it beeps your good to go.

having installed everything except the earthing wire, it has to be a proper earth grounding point as the unit draws 50amps on initial start up. so any td5 owners who know where the nearest grounding earth point in the engine bay passanger side/bulkhead are if you let me know so i can get this damn thing wired up...

many thanks

Why not put it straight on the battery?

believe it or not, they give you enough cable for the red positive to run from engine bay to battery, but the black earth cable is only about 2ft long, so i cant even reach half the engine bay :doh:, either i find a true earth grounding point in the passenger side of the engine bay or i have to start adding cable to extend the black earth side of it to reach one of the other earth grounding points or the battery.

There is no such thing, earths are taken all over the place, bulkhead, chassis, gearboxes...

A TRUE earth grounding point is ANYWHERE really anybit of metal you can find, 50amps is small change to metalwork the size we are talking about.

Based on the location where you need to earth the unit I would suggest one of the heater bolts, or drill a hole in the lip of the wing (there are already some factory holes in it anyway) and put a wee bolt through it...
