v8 disco eats ignition amps

hi i have 1997 3.9 v8 discovery and it seems to have a problem with ignition amps its had 3 in 2 months what would cause it to keep eating them and it seems to be down on power aswell should the 3.9 efi have a resistor to drop the power or is this only on vehicles with points
any help would be great cheers

a balassat resister is not required.
what has lead to the amp failures or is it something else?
spider,dissy fault, damaged wiring?

hi thanks for reply lead to amp is new and dizzy is supposed to be new the spiders been bypassed with proper landy wiring so im lost bloody things depressing me help

have you got it on a remote mounting kit(range rover classic) and have you a thin smear of thermal paste.

Are you sure coil is correct model.

hi 3 weeks ago it had a module and coil local motor factors said the coil was listed as been used with the module he supplied. what goes wrong with the dizzy the bloke i bought it off said it had a new one it looks fairly new. its fairly bad on fuel aswell. yeah its got the paste on aswell

where is the amp mounted next to the coil or on the dissy?

on the dizzy matey

is there another on the coil next to the rad as well?

no just on the dizzy mate

all 300 series disco1 v8 had the amp mounted next to the coil near the rad ensure the wires are in the corret terminals on the amp plug apart from that it could be down to heat that it is failing i know sounds silly but are they pattern amps or genuine items? is it on original dissy cap leads and rotor too as these cause somany problems as well

hi there pattern parts its made by intermotor i got it from andrew pages. ive got some wires near the coil theres a red a blue that go to a blue plug theres never been anything connected to them since i got it it would be nice to now what should be there cheers
