[SV650rules]

Have had the RR851 series R/R from Electrex World on the bike for about 2 years now - I have a permanent digital voltmeter ( like this - https://www.amazon.co.uk/JZK-Motorcy.../dp/B09V2SHF67 ) hooked direct to battery terminals ( I have an SAE charging lead hooked up to battery and just fitted a matching SAE lead on the voltmeter wires, so just plug in voltmeter before I start the bike for a trip ) and also used the 'direct to battery' fused loom ( supplied with R/R ) to cut out resistance in normal loom on bike. As well as running an average of over 30degC cooler the R/R appears to respond to state of charge of the battery. Just after starting the SV the voltage from R/R is about the 14.5 / 14.6 level, after a mile it starts to drop and settles around 14.1 / 14.2, voltage is very stable all across rev range - very happy with the R/R and it was less than £100 when I got it.
