Re: Pertronix Ignitor OMC ESA "Fix"

the solvent for the silicone in a tube stuff is acetic acid (fake vinegar).. interesting what u say thow.. i have only seen it used with small low voltage components.. never thought to use it with mains power stuff.. i will do a google and see what i find..<br /><br />trog100<br /><br />ps.. yes apparently the stuff u buy from harware stores uses vinegar as its solvent this can cause mild corrosion during cure.. u can buy special electrical usage silicone that uses a different solvent it seems..

Re: Pertronix Ignitor OMC ESA "Fix"

so bottom line is...? should we build these in a box with a shock absorbent such as epoxy or just tube it. My suggestion would be to build two and have a spare on board.

Re: Pertronix Ignitor OMC ESA "Fix"

Ok,<br />I am going to see what I can do with this. These are the the main components I'm starting with (Radio Shack Part #'s);<br /><br />(1) 270-1801 Project Box<br />(2) 271-1124 Resistors<br />(2) 276-1144 Diodes<br />(1) 276-0159 Board<br />(1) Weather-Pack 3 conductor male connector<br />(1) Weather-Pack 3 conductor female connector<br /><br />I'm going to try to incorporate the weather pack terminal into the side of the box for sealed connections and to try to make it look like it could be OEM (if you don't look too close). Hopefully, I'll post pics of the final product in a few days.<br /><br />Dave<br /><br />

Can someone tell me if this looks like it will work. I have not soldered anything on yet. Any tips for doing this differently/better would be appreciated. <br /><br />Dave<br /><br />

Re: Pertronix Ignitor OMC ESA "Fix"

yes.. it seems to follow your original diagram.. two caps in series to the module and two reistors in parrallel going off to ground between the caps and module..<br /><br />kinda of an overkill arrangemnet for four little components but it will work.. are u gonna wire from the ground point on the circuit board to the box fixing bolts which could then bolt to engine earth somehow..<br /><br />also a simple solder bridge across two or more tracks is easier than wire loops.. u just need to scrape of the lacquer insulation where u do the bridge.. in case u dont know u can also cut the copper tracks with a sharp knife to break circuits u dont need connected..<br /><br />trog100

trog,<br />Thanks for the reply. I realize this is overkill, but it's for a customer and I don't want any problems. <br /><br />I thought about grounding it through the mounts, but its more trouble than just having a ground wire.<br /><br />This is my first attempt at any type of circuit board, so I appreciate the tips.<br /><br />Thanks,<br />Dave

Plus you'll be able to show it to the customer and he'll think you have the skills of an electrical engineer!<br /><br />p.s. for completeness, how about putting the price next to each component you listed above?

Re: Pertronix Ignitor OMC ESA "Fix"

yes.. with a seperate ground/earth wire u can mount the box anywhere u like.. thow if the box is metal and is earthed (depends where u mount it) it would make sense to limit the wires to just one going in and one coming out..<br /><br />just for anyone else thinking of doing something similar.. that circuit board isnt ideal.. it has over-complicated a simple circuit.. i had to look hard before i dare comment as to whether or not it would work.. he he..<br /><br />when u go poking around radio shack or wherever.. u mostly end up with what they have.. not what u want.. which i assume is what happened to dave.. <br /><br />trog100

Re: Pertronix Ignitor OMC ESA "Fix"

Well, here is the finished product. Final parts cost about $15.00. I mounted the weather-Pack terminal into one end of the box by cutting a hole with a Dremel tool and epoxying the connector in. It looks a little funky, but not too bad. Have not tested it yet.<br /><br />Board soldered and coated, ready for installation in the box<br /><br />

trog,<br />I'm thinking just some double sided foam tape or maybe velcro. <br /><br />Dave

Re: Pertronix Ignitor OMC ESA "Fix"

yep.. either will do in a clean heat free enviroment.. another option would be plastic cable-ties heat or grease wont bother them..<br /><br />i mounted an ignition module to my front engine lifting bracket.. foam double sided auto trim tape and a couple of cable-ties to make sure.. he he <br /><br />that stuff they sell for fixing external decorative trim to cars is the strongest double sided sticky tape u can buy.. magic stuff.. he he<br /><br />trog100

"another option would be plastic cable-ties heat or grease wont bother them.."<br /><br />With all due respect Trog, I have seen thousands of nylon cable ties degrade and become brittle due to heat. Double sided tape has the same downfall, heat kills it. I think the best way to go would be to screw the box into something then put the cover on, it aint goin nowhere then.

Re: Pertronix Ignitor OMC ESA "Fix"

it all depends where u are gonna put it wynter and how much heat i spose.. nylon which is what those ties are made of is pretty tough stuff and when u think how hot a car bodywork can get in summer time without the external trim falling off the tape must be pretty tough stuff as well.. folks might not know but most of that fancy trim that outlives the rest of a car is stuck on with double sided tape..<br /><br />but u are correct.. bolting the box on would be more secure.. and not that much trouble.. thow i am pretty sure my own trim-tape and cable-tie little box aint gonna go anywhere..<br /><br />trog100
