Fitting Bestek Ignition SystemNot even firing
Posted 01 January 2012 - 04:18 PM
Secondly I'm hoping you guys can give me some advice regarding the fitting of my new Bestek dizzy, coil and amp.
I removed the old distributor and carefully marked the position so the new bestek one could be fitted in exactly the same position, which I did. Now here's where I think I have committed a school boy error, should I have turned the crank so that piston number 1 is at top dead centre indicated by a mark inside the dizzy and the rotor arm (hope that makes sense), and if so why would this matter on the old dizzy when I'm fitting a new modified one.
I have checked that all the other wiring is correct (i.e. coil to bestek amplifier, amplifier to dizzy) and that the earth is good. I even took the opportunity to fit new HT leads at the same time. Talking about HT leads although I'm certain these are the same as when they came off the old dizzy, does any one know how I can check this?
I thought these Bestek systems were plug and play because they are simply a higher powered replacement for my standard electronic set up, so I have obviously committed some school boy error somewhere.
When I crank it over the engine doesn't even attempt to fire
All suggestions are very welcome as I plan to sort this tomorrow.

find engine timing mark on front pulley and align with timing mark (TDC) on case.
that will get No 1 AND No 4 pistons to their highest point, but you need to find out which one is on its compression stroke.
think the easiest way would be to remove cam cover and look at the cam, if cam lobs for No1 are facing upward (away from the cam) its on TDC firing, if not turn the engine 360 until the timing marks align again.
you can now remove the distributer and fit it back in so that when fully home the rotor points to the afore mentioned mark, that should now be firing No 1.
this should get you started (put the cam cover on first, or you will get covered in oil)
timing should now be set accurately with timing light
have fun let us know how it goes

Just for info the South Yorkshire'ish mob have a group Timing light you are welcome to borrow, currently in my possesion, let me know and I can bring it up on Weds if you want it.

Rob, that would be excellent if I could borrow the timing light on Wednesday.

My Bestek box of tricks has been programmed to provide 15 degrees advance at tick over and 34 degrees maximum. Does that mean I should set the dizzy timing using the timing light at 15 degrees btdc while the engine is ticking over?
Thanks in advance,

The bestek system has two plugs, one to dizzy and one to coil, and the can only be connected one way. The only other connections to the coil are one for the rev counter. These were fitted to the existing coil which worked perfectly. Now the small racing battery is flat, doh!!!!
Mower man thanks for the offer but I am working the rest of this week and my garage has no power as it is a lockup, so would be fumbling in the dark.
Any more suggestions?

Does this matter so long as the rotor arm is lined up with the timing mark?

thats right, rotor goes clockwise, so leads go to plugs in firing order, 1-3-4-2,
if you are still getting nothing, you better check the dizzy wiring, you mention the wire from coil to dizzy and mention the only other wire is to the tacho, how does it get its feed?
standard system is ignition to + on coil, - on coil to dizzy, tachometer wire on -, coil is switched off and on by contacts (switch) in the distributer.
electronic ignition just replaces the mechanical switch, (I know the Bestek does other things), but will need its own ignition live.
Bestek site gives no detail of wiring, so just a thought, have you a live to the coil still? and one to the dizzy?
