Insulation Resistance of floodlights

[Davetherave]

I keep getting short circuit between live and earth. I can't work out wether this is normal or a genuine fault. Unfortunately I can't lower the floodlight to inspect further. Can only test at the bottom of the base. Can any one help?

......ested at 250V

0.14 ohms

Doesn't sound right, unless you paid a fortune for it I doubt your tester is capable of distinguishing such a low resistance on the 250v test range.

I Might have had too much beer (Slow week) but should that not be 0.14 Meg ohms? 0.14 ohms is rather low lol

Exactly. Hence asking for clarification from the OP. He says 0.14 ohms, which then raises a whole lot of additional questions to enable us to try and work out what's happening.

0.14 ohms

Well if it's really 0.14 ohms L-E and the light works, the CPC must be O/C somewhere and there is a risk of exposed bits being live. If this is not obvious to you, I suggest studying a bit more about testing before undertaking this kind of work.

...I think he's gone to purchase a non-conductive ladder...:conehead:

Not sure why he is testing IR on the cable drop. The light
works, leave it alone!

OK so you walked over to a random floodlight that was WORKING and thought hummmm im going to do an insulation resistance test on this working light????
WHY MATE ???
Alternatively if you are part of the electrical trainee Nerd Herd then leave the flood well alone and let it continue working normally as it is before you do F it up !!
