Direct Volt Adapter Schematic Needed

[Ziggy3]

I read a message in the General Outboard Discussions (non-repair topics) Forum under the topic of CD Ignition (http://www.outboardrepairs.com/topics/007881.html) posted by Schematic regarding a Direct Volt Adapter (DVA) circuit. In the message, dated 2002-03-10, Schematic makes reference to a schematic that he was going to create to help 12Footer with an ignition problem. I would like to get a copy of the schematic if possible. Does anyone have a schematic for a DVA (peak voltage) adapter? Thanks.

Re: Direct Volt Adapter Schematic Needed

Welcome to the board, Ziggy.<br /><br />I've found this one to work for me. When testing the +200v or so you often measure on an outboard, I use a 1/100 resistor divider network in front. Say 220K (1/2W) and 2.2K. Just plug your VOM in the other end.<br /><br />That circuit will work up to a supply voltage of over 15v, and draws hardly any current, so it runs fine from a 9v battery.<br /><br />You'll want to replace the left hand 0.1uF cap with something much higer for slow signals. I find something around 47uF useful around engines.<br /><br />Good luck!<br />(If Schematic has something, I'd certainly like to see that too!)

Paul,<br /><br />Thanks so much for the reply. I'll gather up the parts this weekend or early next week and give it a go.<br /><br />Schematic, can you post your circuit please?<br /><br />-Ziggy
