charging tsunami capacitor

I have a Tsunami Litewave 2 farad capacitor, i lost the charging bulb it came with... Metra tech support said use a 470 ohm resistor, tried this to no avail. Anyone know what might charge it?

How do you mean "to no avail"? What makes you think it didn't charge? If you can disconnect the resistor, and using a meter read 12V across the terminals, it's charged...

Otherwise, you can use ANY light bulb, if you are looking for a visual indication of it's being charged. Connect the positive to the battery, and a test light from the negative to the chassis of the car until the light goes out... Easy.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Charging a 2F cap with a 470 ohm resistor is going to take a while.   The only reason they tell you to charge the cap through a resistor is so you do not De-Blingify your shiny capacitor.  Disconnect a battery terminal and connect the cap.  When you reconnect the battery, this will charge the cap and if there is any De-Blingification caused, it will put an arc mark on the battery or the battery terminal. 

It's supposed to beep while charging and dispay the voltage. With the 470 ohm resistor, i get nothing.

Use a test light. Forget the beeping, as it might not beep until you reach a threshold voltage, which, as mentioned will take a while. Really, just go buy a 99 cent test light at your local autoparts store, and charge it with that. The circuit that drives the beep and the display will very likely pull more current than the resistor is willing to allow through it... It's the VERY same as powering too much amp from too small an alternator.

(The display CAN'T light until you reach a threshold voltage, either. You are really making this FAR too difficult on yourself. Go get a test light...)
