... Mosfets might be rated 200 Ampere (Like the irf 1405) http://www.irf.com/product-info/datasheets/data/irf1405.pdf But as you can see at the end of page 2...
Hi All I've got Richard's Pic Pulser up and running, quick and easy to assemble! I'm still interested in building Rick's Pulser 05 with the battery condition...
Hi Charles. Â The V0.5 pulser looks cool, but was more of a test bed. Ultimatly, it is obsoleted by the low parts count model. Â Yahoo removed the zip file...
Where can I find an assembled unit for sale in the US That can be used on 6 and 12 volt batteries? I just found out about these an hour ago. And this group...
Hi Condeeg, that means that that other newbie Nigel Dawson is a moron, a dork without manners, at least without good manners. But a tip for you, before asking...
Hi condeeg I hope you find the info you require Bruno's comments are a good guide to forum chat. Read loads first and then ask sensible questions. I'm nut in...

apparently the link that i previously sent doesnt work..you can try doing a search on ebay for wizbang...or go to the website http://www.wizbangplus.com/.......
Condeeg, I wanted to refine, if I may, part of Bruno's note to you about where to type your replies when you do reply. Because, this is more a matter of "good...
Hello and thankyou to this group. After nearly a year now of lurking around desulfator boards and postings I am about to receive (should God and the New...
Hello spartakplutonium   If you feel you must, you should use a constant current charger of about 300ma. A constant voltage charger is not a good idea as...
... about 300ma. A constant voltage charger is not a good idea as it will put out it's max current until the battery voltage rises, and if it doesn't rise...
The photo's for this post are under 'Graham's' in the photo section. The Courtiestown kit is very good, it arrived somewhat scantly packaged for a 12,000 mile...
Are you saying that you have attached a 13.8V power supply to a lead acid battery with a shorted cell? Isn't that drying out your good cells? Is the battery...
Hello everyone, I have bought a few of the 555 timer circuits and a pic version from courier in the uk and have an issue. I shelved the pic desulfator for a...
Switching a FET for a bipolar transistor will make a huge difference in the circuit operation. Typically FETs are much faster & require less turn on energy....
Well I guess that's what I get for doing these kinds of things late a night when my mind is restless! D'Oh! Well I thank you for pointing out the blatantly...
I realize this isn't EXACTLY on topic but I feel it is in the spirit of desulfating. My question is where do you get your batteries to work on? Or more...
One way of checking an inductor for shorts is to dab it with a voltage from a low impedance source and monitor the waveform on an oscilloscope. If the ...
Rob, If you've taken out the original MOSFET it's likely you've damaged the 2N3904/ 3906's as well. Regards Richard ... it ... hot ... clamps. ... volts. ... ...
Thanks, but I've replaced both the MOSFET and the transistors already, only I have replaced the MOSFET with a transistor inadvertently and I don't have a...
Hi, I recently built a couple of PIC Kits from courtistown to fit to my Boat Batterys. It's a liveaboard with a 24v 190Ah system and a Stirling Charger/PSU The...
