DO NOT CONNECT THE DESULPHATOR TO THE BATTERY CHARGER – CONNECT IT TO THE

BATTERY & THEN CONNECT THE CHARGER. MAKE SURE THE BATTERY CHARGER IS

UNPLUGGED FROM THE MAINS SUPPLY BEFORE CONNECTING/ DISCONNECTING

1. Check all components/ parts as listed above are present, if in doubt, contact us. Please note the non-

LVC circuit as used in this kit omits IC2, C6, D1, D2, D4 and R8 and R9.

2. Carefully remove the 555 chip from its DIL socket, do not insert until after all soldering of both the

socket and immediately adjacent components is complete. Please note that the 555 should be

inserted with the dot (indentation) on the device nearest to C2 on the PCB.

3. You have a choice as regards output connection. The PCB is currently supplied with 3.6mm holes.

To solder the M4 nuts and bolts to the PCB you will need to drill out the two 3.6mm holes marked –

ve and +ve to M4. Then place a bolt through each hole and secure tightly with a nut. The bolts take

a fair bit of heating but the solder will take eventually. Solder the nut to the PCB to ensure good

continuity. Be aware to let the bolt and solder cool down afterwards. The alternative is to solder your

output lead direct to the PCB which is preferable but makes changing the leads more difficult.

The remaining two washers and nut should be used to enclose a M4 eyed ring connector for a good

solid electrical connection.

4. Components can then be inserted in any order; obviously excessive heat should be avoided. The

MOSFET should be soldered in last though and should not be ‘overly’ handled. In my opinion they

are not as sensitive to static as some might have you believe.

I’m assuming you are aware that the band on an electrolytic capacitor indicates the negative! In the

case of C4 the banded side should be closest to the C5 position.

5. The output diode D5 should be mounted with the banded end towards C4. D3, the reverse polarity

diode, should be mounted with the band towards the +ive output terminal as per the photo below.

6. The LED positive is the longer lead. The long lead should also be mounted nearest C4.

7. C5 allows the high frequency bits to pass more readily than through C4.

What will produce a greater gain would be fitting a larger C4, up to 6,800uF/ 25V has been

recommended. It certainly provides a greater store of energy. If you go this route you would be

advised to fit a potentiometer in place of R2 to allow you to adjust the pulse if necessary i.e. the

inductors or MOSFET start getting hot.

8. There is not a great deal of clearance between the output lead of D3 and the +ive terminal especially

if you use the M4 bolt option. The gap is adequate but I would suggest that you solder the end

nearest the –ive terminal first then crimp the output lead to the body of the diode with a pair of suitably

sized pliers prior to soldering it and insulate the lead as illustrated in the photo.

9. The resettable fuse is the mustard coloured small disc marked R60 or RX90 – this should be soldered

across the points marked F1 with the leads as short as possible.
