Is it possible to test a set of HT off the car?? If so how do i do it & what should i be looking for? The leads in question are Beru leads off of a Cossie!!
Any help much appreciated

Only way I can think of is using a multimeter to check resistance of core is virtually zero and then a megger to check insualtion resistance is infinity.

 

check the risistance with a multi meter any think over 11k and there in the bin

 

is that true as they will all be varying resistances due to thier lengths been different?
thanks

the actual core resistance is negligably nil. the resistor is in the boot itself (and these are balanced to each lead to ensure they are all the same). cant remmeber off the top of my head ) 5 kohm rings a bell. -but they should ALL measure the same as they are balanced leads. cheaper silicone would leads WILL vary in resistance w.r.t. length as the core IS the resistor.

 

thanks for that.
i measured the resistance on my fiesta leads(standerd ford) and they go from 16K on no1 down to about 8K on number 4.
thanks

Cheers for the help Guys..
Measured the resistance of My Beru leads & this was the result..

Lead No 1 = 5.83 Kohms
Lead No 2 = 5.57 Kohms
Lead No 3 = 5.77 Kohms
Lead No 4 = 5.83 Kohms

Looks like I've got a good set

they are bang on 5k brand new and anything over 11k is scrap

 

Manual says 4500 to 7000 ohms....
