Morning, I was wondering, would I be able to use the DC output from this Modcharger to run my SIP speedo?

Is this because you want to run the SIP speedo off DC, or because you believe you must run an SIP speedo off DC?
I don't have an SIP speedo, but my understanding is that they run off AC, and if you want to run them on a DC system (such as Wassell rectifier/regulator) then there are some small changes that you need to make in order for it to work. There was a long thread about overcoming issues with SIP speedos on DC systems. Use the search function on this forum (or was it the LCGB forum?)

Mine does run on AC but I was hoping it might run a little better if on DC - it tends to fade a bit on tick-over - I just thought I would ask the question whilst I have my headset off to tidy up the electrics in there.Knowledge wrote:Is this because you want to run the SIP speedo off DC, or because you believe you must run an SIP speedo off DC?

The rev counter needs an AC feed but the power feed can be either ac or dc. I ended up running off a battery which is charged by the dc circuit as tick over output wasn't enough to power consistently.

Same as above I just put the Rev counter feed on the inlet side of my wassel

I have Wassel conversion and have spliced the tacho sensor into one of the yellows before the rectifier. Seems to work fine.
