    How to modify 12-24v car phone charger?

    I have one more question, can I modify my existing 12v power supply to give me 14v or so to charge my 12v battery? We would have to know more about it to determine if there is INITIALLY being that high of a voltage being created within the unit. 73's de Edd

    Can't find this symbol

    I will say that if this was plugged into a Prick 68 That the wiring interfacing would be into stranded 20-22 AWG sized wiring. Fully relying upon my 50 year memory. The miniscule power being involved was the grounding of " C " wires connection to a relay coils winding within the transmit...

    Soldering Problem

    In that products endeavor in disguise within its MSDS postings info. I am HEAVILY in suspect if it's white coloring aspect, as being content of my earlier mentioned ammonium chloride. It has been used for the facilitating of cleaning soldering irons w..a..y back, starting in the 1920's. It was...

    Circuit diagrams of TORO DDC-4

    Mme zulu . . . . . To be sure that I catch all, I am going to fill in between your entrys. It seems that now the AC crosses the relay, arriving at L1 and, on the front side PCB track, stopping at C5 (the first of the 2 capacitors in series), >>>Pass back the marked on voltage rating on that...

    Bypassing a momentary switch

    . Sir tasehr . . . . . . . That designated relay will certainly provide the required isolation that will be needed. BUT I asked about your capability-materiel and expertise, for the additional little amount of electronics circuitry construction related to providing the DELAY aspect in the...

    Help fixing old walkie talkie

    You are just fine then. Since it ended up being slightly above the board a bit more than the other one, I just wanted to be sure that it got its metal outer shell, grounded.

    Help fixing old walkie talkie

    Sir ATA . . . . . . . No no no . . . . .I was mentioning that was the ONLY option that there was, until THAT unit was found. As I said, all that I see that you need to do is confirm that the now floating, corner pcb foil which is being cold terminal (#19 on the Sams schematic above). No...

    Car amp repair

    Sir static. . . . . . . Do I connect a meter to test these caps, and then test with power on then off so as to make sure I am getting power to the caps? The two caps are the storage reservoir caps for the negative and positive power supplies and the side by side capacitors are sharing...

    Bypassing a momentary switch

    Sir tasehr . . . . . . If I hold the momentary switch in when applying power I get an E1 error since the switch is not released. For further clarification, you get that E1 error and therefore, the AC wouldn't power up and come on ? But just as soon as you release it and press again the unit...

    Bypassing a momentary switch

    Sir tasehr. . . . . . . Soooooo I wasn't familiar with that switched power item, so I had to really-search it. Like: The Leviton DZPA1 is a Z-Wave enabled universal switch designed for use for most residential lighting and motor applications. A large range of load types are supported...

    Car amp repair

    Sir static . . . . . . . That formulation is one of the BETTER glues . For starters look at the new YELLOW square designated capacitor pair. With the board now being "naked" of heatsinking. Use DC voltage reading of metering to be connected across one and then the other "YELLOW"...

    Sir ATA . . . . . . . At that time that coil was the only one being offered and to be found . . . .in all of the world . . . . I do believe. That was a transformer for a CB RF amplifier stage. It looked like a direct drop in, size wise for the old unit, but it now is seeming to be a wee...

    JVC AX-R551X PROBLEM

    I see that there is just but a trace of ripple carrying on to the other side of R916. The idea on the testing across Ry901 was to use a DMM across it for the measurements. To see if there was being any voltage change across it, from initial power up, on until a couple of minutes. If you happen...

    Bypassing a momentary switch

    Sir tasehr . . . . . " I'm just wondering why you need to do it?" . . . . Me too . . . . .and isn't this being a Haier unit . . . and what is its model number ? Is it a situation of there being a power loss and with several units . you have to travel to each unit to start up each unit...

    How to modify 12-24v car phone charger?

    Rosin flux is an effective flux for electronics work, while some soldering "pastes " are quite aggressive. So if you happen to use one of those, you have to be sure that the joint is WELL-WELL-WELL cleaned after finished. The aggressive pastes will have Zinc Chloride and Ammonium Chloride...

    Sir philadelphia1. . . . . . . O.K. then maybe we can dumben my prior info down a bit . . . possibly then being one level up from: "I do not like green eggs and ham. I do not like them, Sam-I-Am." Referring to your photo just above, lets just see if that top portion circular foil land...

    O.K. just for you ,applicable to YOUR iron and YOUR situation. Fully taking advantage of the laws of quantum physics and mechanics . . .to further assist. Yes, I was referring to the new tip, since you seem to be unable to get it to take a tinning. Plus, the old tip, seems to be nearing the...

    How to modify 12-24v car phone charger?

    I can see the " blued " area, from prior heat concentration. This might be a plated tip . . .but EVENTUALLY, one has to file or scrape a tip to re use it. Install the tip: Scrape a little area clean, that is right up against where it comes out of the barrel of the heater tube. Will it...

    Sir Philadelphia 1 . . . . . . . You do know that you are working with a probably "UNOBTANIUM " / NLA circuit board . . .don't you ? After looking at your component extraction prowess . . . . I believe that EVERY foil pad on the board is quaking and saying . . . . . Get the hell out of...

    Sir philadelphia1 . . . . . I am just hoarding my "60/40" solder, in case the " no lead advocates " make it harder . . .and more expensive . . . . to get in the future. I'm suspecting that heat is taking most of them out more often than not. My multi decades of experience and failure...
