Name of part?

[JeremyNeale]

I am currently fitting a set of dashboard dials to my boat. The engine is a 1986 4 cyl merc classic 50.<br /><br />In a fit of trademark stupidity i shorted a live onto the RPM sender wire and fried the component.<br />I have identified the part i fried (small cubic electrical box). The grey wire that sends the RMP signal to the control box fastens to it.<br /><br />The problem is i want to order a new one but have no idea what it is called!<br /><br />Any help much appreciated....

Ok, so it seems i can get this part 100% cheaper if i order it in the states (I am in the UK)<br /><br />The dealer (dougrussell.com) says there is no shipping cost?<br />Does anybody have experince of purchasing US parts for international shipping? Will there be extra to pay like VAT and duty when it arrives on the door step?

Jeremy, A Full Wave Rectifier is a fairly standard electronic component. Every Auto battery charger has one. I fried my Mercury rectifier 20 years ago and replaced it with 25 Amp full wave rectifier that I purchased at a local Radio Shack for $4. The replacement was much better and much cheaper than the Mercury part. The only difference is that the replacement rectifier has four terminals(AC,+,AC,-), versus three(AC,+,AC) on the OEM part. Mercury grounds the fourth terminal to the rectifier body internally. If you buy standard rectifier, will need to ground the "-" terminal to the motor chassis (Negative Earth for you Brits)
