Datel DVM wiring options
I just received my Datel DVM. Round style with 2 wire connection. I have a 2007 PDS and was wondering what is best option for wiring.
A: direct wire (on all the time) B: direct wire with separate on/off toggle c: wire thru key switch (not sure if I will be getting true reading) I currently have a bar style SOC meter but have upgraded to 48V and needed new meter. Best option? would prefer to wire to switch, if I will get an accurate reading. Thanks Dave |

Re: Datel DVM wiring options
best to wire it through the key switch

Re: Datel DVM wiring options
In a stock PDS, the voltage to the keyswitch comes from the controller, so it may vary a bit from pack voltage.
Check it to be sure. |

Re: Datel DVM wiring options
I'm not stock, following upgrades alltrax 500 controller, ge 1162, hd 400amp solenoid, weld leads for cables and delta q charger. so is the voltage coming thru switch going to be what the pack actually is?

Re: Datel DVM wiring options
I don't think so. I have a dedicated pair of 16ga wires (with a fuse) running from the pack to behind the dash, which I now have switched by a relay, activated by the key switch. I measure my voltage from that, but as the accessories I've installed will load that wire so I'm going to see what impact they have. If needed, I'll run a 2nd, dedicated pair just for the DVM to make sure that it's reading straight off the pack..

Re: Datel DVM wiring options
The pack voltage goes through the fuse in the charging loop (if it exists), the Reed switch, the Run/Tow switch, the F/R switch and a diode, plus four in-line connectors before it gets to the keyswitch.
The diode alone drops the voltage by 0.6V, which is roughly 15% SoC. I ran my DVM battery meter straight to the battery pack and it has been running almost continuously for about 2 years with no visible degradation in readability. |

Re: Datel DVM wiring options
OK, straight to the pack and probably put in a fuse and
A toggle switch to turn on and off. Thanks |
