SX4000 - Sparkrite SX4000 Universal Points and Electronic Ignition Amplifier Module
The Sparkrite SX4000 is an Electronic Ignition system that can be fitted alongside any 12 Volt negative earth points ignition system.
It gives all the benefits of electronic ignition without removing the original points/condenser ignition system. This means it can be switched back to running on points at the flick of a switch, so you always have the reassurance of points back up if any problems should occur.
How Does the Sparkrite SX4000 work?
In a traditional points system the points have to carry the full voltage of the ignition system. The point’s gap is critical as it determines the dwell time for the coil. This is the time the coil is connected to ground allowing it to charge between each firing, every time the points open and close a spark can often be observed, this can cause damage to the contact surface leading to failure. In addition the point’s heel is constantly wearing closing the point’s gap and altering the dwell causing reduced performance.
The Sparkrite SX4000 diverts the high electrical current away from the points and controls the dwell time electronically, constantly adjusting and giving the correct dwell time.
The points now only having to deal with a tiny current so will not burn and will last indefinitely. The point’s gap now only needs to be roughly correct, as dwell is now electronically controlled. It will only need very occasional adjustment to take up any wear of the heel.

After SX4000 installed my car become excellent performance
Hi, I called and advised that having purchased 2 SX4000 units, I fitted 1 to my MGB. It worked well for 5 Miles, then I changed the points, reset the timing etc and then it had a bad misfire. The LED still works as described in your instructions. I switched back to bypass the electronic ignition and the misfire has gone, having been on the Spring Run on Sunday 7th for 150 miles. I am removing the first unit, will fit the second unit and advise further.

As explained to David my 1969 Ducati 450 single cylinder motorcycle is undergoing some restoration. Your Electronic Ign kit is a part of that resto. So, as yet, I haven't yet run the kit. But, the quality looks excellent and it 'looks the business' installed. The printed installation info and your info by email has been great. So I am optimistic all will be just as I hoped for. Also, thanks for your prompt service.
Brilliant! Transformed my ailing LPG forktruck with obselete engine and parts only available from USA with horrendous price & postage.
