This LRO reader emailed LRO.firstname.lastname@example.org to ask our experts for advice on wiring from the alternator to the battery in his Range Rover Classic 'Hybrid'.
I own a 1972 hybrid Land Rover based on a Range Rover chassis. We fitted a 2.8 turbo Daihatsu engine, which proved a better choice than the standard 2.25 it replaced. The problem I’ve got is that the battery is not charging; the alternator is new, but the problem still persists. The battery is also new; not wanting to buy another alternator, I got it bench-tested and it was confirmed as fully operational.
Could the problem be with the wiring? There is one heavy black wire from the alternator to the battery via the starter motor; could you give me some advice on how the wiring runs from the alternator to the battery, please?

These Daihatsu alternators need more wiring than the standard Lucas/Land Rover ones. You will find a B+ for the main lead for the battery, a connection for the warning light marked any of the following: WL, IND, D or DF. In addition, there will be an ignition feed marked ‘I’ and a sense wire marked ‘S’, which must be run direct to the battery positive. A thin wire is fine.
