instead of using various value of capacitor to get total 33000 mikrofarad, why not we use one cap with value 33000 mikrofarad for example la. Got any diffrent between ka? how about the resonance ?
it supposes do the same thing as SARD sweeper, after all, I opened a SARD sweeper and mod this one
the electricity generate from automotive alternator has a frequency like black curve on figure 1,
with these capacitors helping out we can make the current less ripple and more or lese come to green line
figure 2 is the resistance formula for capacitor(s)
figure 3 is probably the most effecient way for capacitor to share and stablizing the ripples
some users of HKS version report loss power when engine reving over 6000rpm, so I went to test my setup earlier tonight, however I didn't get to go that fast when i spoted flashing lights around next bend on the highway
I went overboard and triple the caps used on my setup over SARD one, so here are the caps spec.
4700uf 16V 105°C *6 (2~3 should be enough)
3900uf 16V 105°C *8 (none in SARD version)
3300uf 16V 105°C *6 (2~3 should be enough)
2200uf 16V 105°C *8 (none in SARD version)
1000uf 16V 105°C *6 (2~3 should be enough)
wiring diagram? look above on figure 3, just connect all negative of cap on the board with soldering iron, then connect all positive side, try to draw it so the middle part of both path are on the side and easily attach a foot of 10AWG(I used 8AWG) cable on the middle and to the side of casing
black wire to negative post on the battery and red wire connect to positive post on the battery. Be advise engine brake would be a little fade once this device installed, but you should notice engine is running a lot smoother and more powerful on start and/or AC/audio is on.
I will be testing on 4AT and NCVT models later this week
It seems that shops in Jalan Pasar do not have the 3900uF capacitors.
Is this a mistake in the value?
Where did u guys get the caps from? :shocked:
how do i know wheather the VS is working ar ? my one install then the LED light up brightly then slowly dimming ..... then when turn the light on n a/c on the light gone ......
1. Connect ur VS to Car battery, and remove ur VS again... short circuit ur VS (connect ur VS "+" and "-" 2gether), if got spark.. it's means ur VS can store electric current and function. Disadvantage: don't know VS quality.....
2. Use "analog" multimeter, change to "ohm" "X1k" channel, connect red probe to VS "+" and black probe to VS "-". U will c indicator quickly moving to right side and after few seconds or mins (depend on ur VS capacitance, big value will take more time) indicator slowly go back left side... and approach "infinity" value... it's means ur VS working fine and can consider good quality..
If indicator can't turn back to left side, ex: stop at center or right side(zero ohm), ur VS inside maybe got one or few bad capacitor (bad? hard to explain:regular_smile: )... or ur VS totally short circuit.
This way can use by single capacitor quality checking also.
3. Use capacitance measurement measure ur VS capacitance.. if total value = measure value... (tolerance +/- 5% ~ 10%) can consider it's good...
And, edwin can u post ur VS inside picture (u hand made?).... I think ur VS's LED or circuitry got problem... LED shouldn't turn off... even ur car no start... (except ur VS got voltage level detector, can shutdown ur VS when stop ur engine)
thta one i did was like prototype ..... later wan do another one .... i bought the box too big ..... so cannot fit into my wira ..... somemore to many caps oledi ...... 24 caps .... too many oledi later wan do below 20 caps ...... value of 38 - 45 K mF
