hey guys

firstly before i get flamed for not using the search tool...i have

so anyway:
i am going to be wiring up the tacho tommorow. i reckon ill have no problems wiring up most of it (ive allready got a tacho installed, so i can trace wires) but the one thing that has me muddled, is the instructions tell you
"for Points ignition vehicles
when fitting a speco meter tachometer to points ignition it MAY be necessary to fit the enclosed 1 amp rectifier diode"

it then goes on to say that for 'mini minors':
"many of these vehicles will not operate an aftermarket tacho when fitted. it may be necessary to fit a 3amp universal diode in line in the coil wire"



SOOOOO>
my questions are:
1. if i wire up the tacho without the diode (it may not nned it, correct??? ) will this cause any damage to the gauge?

2. should i be wiring up the 3amp universal diode from the very start?

3. (if applicable) HOW do i wire in the diode.....from my research and basic electronics i know it goes on the wire (duh), but do i cut the wire, solder in this diode inbetween the two bits of wire.....OR....???????

Cheers guys

(oh and mods if you wanna move this thread to somewhere else thats allgood)

If you need a diode and don't put it in there is a high probability you could bugger the taco. Put it in anyway - won't harm if not needed

Put it at either end of the connecting wire - no need to cut unless you can't get at the ends - and yes solder the connections and preferably shrink wrap the joins

Don't solder until you have tested it, if the diode is reversed the motor won't run.

sorry i just want to check...
um...so ive got my green wire thats heading to the coil.....do i cut that wire and solder in that diode (after testing which direction it faces) in between those 2 bits of wire??

thanks

thanks heaps for the help guys

installed it tonight....had a few hiccups due to the diode, firstly not facing the correct way, then not getting connection to the wire (what do you expect when a lazy-ass like me puts it in elec tape and expects it to work ) , but now its working nicely.

thanks again
