L4310 Enhancements

No, sometimes I talk on the phone when absolutely necessary, but that's as far as I go. If you haven't used Posi-Lock connectors check out my post under attachments. You comment about ScotchLocks (yuck!) reminded me of them. They're amazing. In addition to simply splicing two wires together, you can also splice 3, 4, or more together with them, depending on the size of the wire and/or connector.

I'm looking into to it. Being an automotive service and repair station I get the napa stuff at jobber cost. But at times this is to much. To many middle men keep marking the price up. If you do find a place please let me know.

Getting pretty excited... New tractor should be here middle of this week.

Rowski - I forgot about the proliferation of middle-men. Rediculous.

I'll let you know. I've got a couple leads I'm trying to run down today.

Be careful which chart you use. The one for house wiring is pretty useless for 12 volt applications. It is based on having a 6 volt drop, which is ok for house wiring, but a disaster for tractor wiring. Best to size the wires by calculating the voltage drop for 1 volt or less drop at the desired max current. Simply multiply the current in amps x the resistance in ohms for the entire two way path of the circuit to obtain the voltage drop in volts. You will use larger wire than you thought. /w3tcompact/icons/smile.gif

Wen - Yeah, I was using a DC auto wiring chart. Good point, though - it definitely makes a difference.

Wen I agree about the wiring charts but a one volt drop on a 12 volt DC system is pretty high don't you think? 1/4 to 1/2 voltage loss at max amps I might buy into and that is after going through a relay or solinoid, but in straight wiring seems like alot to me. But you are very correct alot of times you will end up with a much larger wire size than you first thought. Maybe a volt of loss through a cheap blocking diode but then again that causes a problem no matter what the wire size is.

Yes, the less the better. It is really hard to hold the drop to 1/2 volt. Calculate the drop on a 20 amp headlight circuit that is 20 feet in total length. The saving grace is the alternator puts out considerably more than 12 volts and makes up for the drop. Yes, the drop in diodes is about 0.7 volts and impossible to reduce (unless you have some of the now exotic material diodes). Relay points should be pretty good for voltage drop, otherwise they don't last very long. Terminations are the worse problem and they always get worse with time and after a little corossion. Most failures occur at connectors or where wires burn loose from terminals or connectors. 90% of electronic failures are also mechanical.

Wen good point. V(volts) = I(current)x R (resistance). The electrical golden rule.

Now guys we can't forget about P (watts) P= V+I or Isquared x R . Nothing like getting the old brain working. /w3tcompact/icons/smile.gif

Seems like I'm back in school... But more fun??
I guess fun needs to be defined.
