mcc1979ian Posted February 20, 2020 Share Posted February 20, 2020 Ok chaps so I’m gona finally sort out some wiring on my ‘86 90. Fitting Anderson connector for jump start, second battery with plug for camping etc, isolator switch for the winch. I’m also looking at replacing the earth and positive cables but I’m unsure if 170amp is enough or should I go higher rated? Quote Link to comment Share on other sites More sharing options...
western Posted February 20, 2020 Share Posted February 20, 2020 AA/RAC use the 175amp anderson connectors for their jump cable, so for your use reckon that amp rating cable would me satisfactory. plenty of choices for battery/jump & main feed cables here https://www.autosparks.co.uk/electrical-components/cables/battery-cables.html Quote Link to comment Share on other sites More sharing options...
zardos Posted February 20, 2020 Share Posted February 20, 2020 Sounds fine, except for isolator for winch and winch power and earth. Winch motors can draw more than 175Amp for extended periods of time. Depending on the winch this can be up to 500A, so anything related to the winch should be in 70mm2 really.
