Dave Stampy Posted March 1, 2013 Share Posted March 1, 2013 I've put a v6 in my manta, when I try to start the engine it heats up considerably, do I need to uprate this cable ? Or I heard the sometimes you can get a build up of carbon on the bushes and they need cleaning? Anyone else had a simler problem? Quote Link to comment Share on other sites More sharing options...
Danny D114BCW Posted March 2, 2013 Share Posted March 2, 2013 I am guessing that the battery isnt the right size and is too big. Quote Link to comment Share on other sites More sharing options...
upk Posted March 2, 2013 Share Posted March 2, 2013 Make sure you have a good earth connection from engine block to chassis . If not then you will have a higher resistance circuit which will result in more current pull. Failing that it could be the starter is under too much load or it's on it's way out!

mantadoc Posted March 3, 2013 Share Posted March 3, 2013 What Kev said (mostly). What goes out of the battery on one lead has to be equal to what comes in on the other. Poor connections on earth leads will make them heat up around the connections. As wire getting hot it's drawing too much current. If any of the other leads were poor they would be hot too. Exception is voltage drop is proportional to length and as earth leads are shorter you are less prone to see it. Plus if the earth leads were the high reisstance bottleneck they would choke the flow of current and heat up and the live probably not get hot.
