Wiring car engine from scratch
corrado vr6 - 29/6/14 at 12:53 PM

Hi there,
I have a Suzuki sj413, however I'm putting a jago body on, I've started to look at the wiring and the original loom has been chopped about so much I've decided to start from scratch.

I have drawn up a diagram of how I have got the engine to run which works great the starting wiring is shown below on the left.

Now with the way I have set this up the battery won't be getting charged so I have looked on google and I think I have an idea of how to sort the charging wiring to the alternator

Is there anything wrong with how I'm going about it? Or a better way maybe?

Obviously I know I gauges and lighting etc to sort

PLEASE NOTICE where I have written starter motor for the diagram on the right it should say alternator

Hi again great to see rtgis one progressing as you have prob guessed others hve trodden a very similar route in the past. If you have lots of time and patience your current approach willget tgere- we bought a mini Scamp that had bEen wired one circuit at a time using choc block connectors and it all. Worked fine, if you want to speed things up there are vaarious schematics around to follow- standard car circuits layout on Westfield forum somewhere as we printed it off once and hung A copy on garage wall when my lad was small so he could get an idea why we needed so many wires. Also a fellow called snowy from Dutton Owners Xlub ( comes on here from time to time) also has a we site and diagram for a basic car system.hth

I am no expert but think you may need to add a relay between your start switch and starter motor as DC current will burn the switch out in no time.

That would allow the starter to turn the engine, even with the ignition turned off, I think youd be better to take the starter feed from the ignition switch/kill switch, so when thats off nothing works.

You also appear to have all your switched positives connected to the battery negative

Ah thanks all, I had forgotten about a starter relay so thanks for that

That's a great suggestion about taking the starter feed from the kill switch, thanks!

Whoops that'll teach me not to drink and draw diagrams the next morning hopefully I wire them to the positive when doing this lol
