Fitting New Ign Amp

[Kennyb 0]

Hi Guys

 

Ok i've ordered a new bosch ign amp from peugeot......just a question before I start to attempt fitment.....how do you fit them? is it quite straight forward or will I need special stuff?

 

I've read about thermal paste but having never touched this area im unsure of the process.

 

Any advice would be musch apreciated

 

Cheers

It's held on by two small screws, I undid the old one, covered the back of the new one in thermal paste. Give the area it goes onto a quick clean and screwed the new one in.

It should come with a tube of thermal paste too.

So pretty straight forward then! How (briefly) does the thing work??

Would a faulty amp create a weak spark???

Mines under the coil on an ally plate, if yours is there to, heres what you do! (hah that rhymes!)

 

Whip the old one off (mine was held in place with two 4 or 5 mm bolts, yours mught be screws though .. what ever)

Clean the ally plate up with a bit of 800 grit (or so) sandpaper so its smooth and shiney.

Give the plate a wipe over with brake cleaner

Give the back of the amp a wipe over with brake cleaner to de-grease (spray the brake cleaner on a cloth, not the amp)

Apply thermal paste to back of new amp

Bolt back on:)

 

Much like putting a heatsink on a CPU.

 

I have no Idea how they work, I know jank ones cause misfires that combined with their name ('amplifier') would lead me to think you would be correct in your assumption that knackered ones create weak sparks.
